This is known to cause increase in thirst and excessive amount of diluted urine. To identify conserved targets of biguanides involved in growth inhibition, trental mg yan etkileri we conducted an RNA interference RNAi screen in C. Vydox is recommended to be taken daily as it works in building up strength and concentration through time. Their progression will be carefully tracked over the course of 8 to 10 assessments staggered over four to four and a half years of data collection. The participant sample will be geographically, ethnically, and socio-economically diverse.

The proposal takes a comprehensive biopsychosocial approach to the conceptualization and measurement of risk factors, which include Neuroticism, depressogenic cognitive style, anxiety sensitivity, introversion and low positive affectivity, sociotropy and autonomy. Measures will include self report, parental report, as well as information processing tasks modified Stroop, memory tasks , affective modulation of startle reactivity, and ambulatory cortisol assays.

In 26 Anxiety Disorders addition, diathesis-stress interactions will be evaluated on the basis of contextual assessment of chronic and episodic life stress. Outcome will be measured in terms of symptoms and diagnosis of anxiety and depression. Various models of commonalities and specificities of risk and their interaction with stress will be tested using hierarchical logistic regression and structural equation modeling. The findings may further our conceptualization of emotional disorders and provide the platform for prevention research.

The public mental health impact of living in violent communities is significant, particularly for children. Most of the extant treatment and preventive interventions focus on the perpetrators of the violence, not on the youth who are its direct or indirect victims. Among the psychological correlates of community violence exposure are anxiety symptoms e. This is a request for a NIMH Pilot Effectiveness Trial for Mental Disorders Grant R21 to support a 3- year pilot study of a school-based prevention and early intervention program with inner-city, primarily African American children at risk for anxiety disorders.

This cognitivebehavioral intervention is based on the FRIENDS Anxiety Prevention Program that has demonstrated efficacy in reducing the rate of anxiety disorders and preventing the onset of new disorders in school samples of Australian children. Maintaining therapeutic integrity, the proposed project will broaden the FRIENDS target population by modifying the intervention to be culturally and contextually appropriate for innercity ethnic minority youth exposed to community violence.

Four-hundred 3rd-5th graders will be screened to identify those at risk for anxiety symptoms and disorders. Child, parent and teacher assessments will be made at pre- and post- intervention, and 6-month follow-up. This project will contribute to the applicant's goal of studying and preventing the mental health effects of community violence by achieving the following aims: 1 To broaden the target population of an existing efficacious preventive and early intervention program from Australian children to inner-city, low-SES primarily African American children; and 2 To maintain the therapeutic integrity of the modified FRIENDS preventive and early intervention program among children from schools located in inner- city, high crime, low-SES communities.

The results of this R21 project will facilitate the design and later implementation of a full-scale NIMH R01 preventive intervention effectiveness trial. The applicant's strong academic background in human development, clinical psychology, and psychiatric epidemiology, and her research experience using a developmental paradigm to study risk for severe psychopathology among individuals with early-onset anxiety disorders provide an excellent foundation for this work.

These goals will all facilitate the applicant's pursuit of innovative, comprehensive, technologically efficient approaches to study these comorbidities in youth.

In the third study, the applicant will collect her own asthma data prospectively Network study , in an ongoing longitudinal epidemiologic clinical psychiatric investigation, while learning how to conduct a study. The fourth investigation will involve developing measures and collecting pilot data on asthma and anxiety in a clinical medical sample. The applicant's resulting ROl will address the developmental paradigm described above, which will be further tested and will include early intervention strategies to facilitate the identification and treatment of children who are at risk for severe psychopathology.

This comorbidity is associated with increased risk for several adverse outcomes, including social rejection, substance use, anxiety disorders, and suicide. However, because much of the extant research in this area has been conducted at the symptom level, relatively little is known about the mechanisms of action that are responsible for the observed rates of comorbidity.

Moreover, a number of plausible alternatives obtain. Identifying which of these mechanisms is at work is likely to require the application of several strategies that have generally not been employed in the comorbidity literature to date. These include a distinguishing between childhood-onset and adolescent-onset CD, b expanding the scope of comorbidity research to include biological and physiological measures, c 28 Anxiety Disorders generating and testing mechanistic theories of comorbidity, and d studying the development of comorbidity and its associated symptoms longitudinally.

Studies conducted within this age range are critical, as it represents a period of escalating delinquency, depression, and substance use, which often co-occur. Following from theories of emotion regulation Porges, and motivation Gray, 1 a, 1 b, 1 a, 1 b , patterns of psychophysiological responding will be assessed in participants during conditions of reward, punishment, and social threat.

In addition, extensive family history interviews with be conducted with parents, and measures of child delinquency, symptoms of depression, and substance use will be obtained at each of three one-year intervals. Using these data, the following Specific Aims will be pursued: 1 elucidate patterns of autonomic nervous system activity within and across groups through assessment of appropriate psychophysiological markers of behavioral inhibition electrodermal responding during punishment , behavioral activation cardiac pre-ejection period during reward , and emotion regulation respiratory sinus arrhythmia during social threat ; 2 assess developmental trajectories in autonomic responding within and across disorders, and relate these trajectories to parental background characteristics and parenting practices; and 3 assess developmental trajectories in child substance use patterns, and examine the potential mediating roles of autonomic responding in relations between parental and child use.

Findings obtained should further our understanding of the autonomic substrates of CD, depression, and their comorbidity, and may have differential treatment implications for depressed probands who do and do not present with comorbid CD. Little is known regarding 1 the distribution and determinants of mental illness in the Philippines, in the millions of Asian-American in the U.

Career Development: The candidate proposes 12 months of career development that will include 1 additional training in epidemiology and statistics at The Johns Hopkins School of Public Health JHSPH , 2 new interdisciplinary training, both in medical anthropology at JHSPH and in cross-cultural psychiatry at McGill University, and 3 mentorship and consultation with a panel of experts in psychiatric epidemiology, cross-cultural psychiatry, and world mental health. First, the candidate will conduct an ethnographic mental health study focusing on mood and anxiety symptoms and disorders.

The candidate will interview approximately 75 adult Key Informants, including 1 medical and psychiatric patients, 2 non-patient community Studies 29 constituents, and 3 a variety of health care providers from Region IV and the NCR. Using information from the ethnography, a report will be prepared that 1 describes how Filipinos experience and express mental distress and illness; 2 describes how Filipinos explain the etiology, classification, and treatment of mental distress and illness; and 3 includes a dictionary of Filipino mental heath terms.

The core of the interview will consist of the mood and anxiety disorder sections of the World Health Organization's Composite International Diagnostic Interview CIDI ; however, the relatively shorter and more objective alcohol use disorder section will also be included. Goals of the epidemiologic study include 1 assessing the reliability, validity, and cross-cultural applicability of DSM-IV and ICD based mood and anxiety disorders and methods of assessment in the Philippines and 2 determining what modifications may increase reliability and validity.

Other goals include describing the relationship between anxiety, mood, and alcohol use disorders and 1 social and demographic characteristic; 2 patterns of health care services availability, utilization, and need; and 3 types and degrees of disability and functional impairment. Finally, the candidate will obtain Region IV community prevalence rate estimates for mood, anxiety, and alcohol use disorders. Preliminary data presented here suggest that the elderly in AL have high rates of psychiatric disorders, with dementia being the most common.

These conditions probably contribute to significant morbidity such as functional impairments and caregiver burden , and to early discharge from AL, typically to a nursing home. Dementia and other psychiatric disorders are probably under-recognized and under-treated in AL, in part because of inadequate preparation of the AL care system to address them. There has never been a comprehensive study of dementia or of other psychiatric disorders in AL This study will gather information about the prevalence, detection, and treatment of dementia and other psychiatric disorders in AL residents.

It will study a stratified, random sample of AL residents in Maryland from large facilities, from small facilities and 75 from dementia special care units. Each resident will undergo a comprehensive evaluation for dementia and a standardized psychiatric diagnostic examination. This will produce an estimate of the prevalence and morbidity associated with dementia in AL residents Aim 1.

It will also generate an estimate of the prevalence and morbidity associated with other psychiatric disorders, especially mood and anxiety disorders Aim 2. Patient evaluations, chart reviews and interviews with family and professional caregivers will determine whether dementia or other psychiatric disorders are detected, or treated and how this affects clinical outcomes in assisted living Aim 3. Study findings will likely have a substantial 30 Anxiety Disorders public health impact in gerontology, geriatric medicine and geriatric psychiatry. They will provide essential information about the prevalence and consequences of psychiatric morbidity among assisted living residents projected to approach 3.

This information is of great interest to healthcare providers, licensing agencies, policy makers, the assisted living industry and the general public. It is likely to affect clinical practices in assisted living resulting in the implementation of assisted living-based screening and treatment programs for dementia and other psychiatric disorders that will benefit residents, and may delay their discharge from assisted living facilities to nursing homes. The application has 2 phases that encompass 3 specific aims. Also included during Phase 1 will be efforts to finalize and empirically test procedures to ensure therapists' adherence and competence in using the treatment manual including measures to assess adherence and competence - Aim 2.

Participants will be diagnosed with the Clinician Administered PTSD Scale and will complete a battery of additional clinician and self-report measures before and after treatment. Phase 1 will be an iterative process across the 3 waves of 5 cases each. After each wave, the treatment manual and measures of adherence and competence will be refined.

Outcome will be assessed using clinician measures of PTSD symptoms, anxiety disorders, and depressive disorders. As well, participants will complete questionnaires evaluating PTSD, anxiety, depression, health care utilization, and pain. Additionally, it is hypothesized that patients who receive Group CBT will maintain these gains at 3-month follow-up. Examination of intent-to-treat participants will permit initial evaluation of the acceptability of Group CBT. Because MVAs are the single leading cause of PTSD in the general population, this application has the potential to provide a cost-efficient treatment.

The research goal is to place preschoolers' anxiety symptoms and disorders within the framework of developmental epidemiology by focusing on two questions: 1. What are the age-specific presentations of anxiety disorders in children ages 2 to 5 years old? Nosology 2. What are the relative contributions of genes and environment and their interaction in the early development of anxiety disorders?

Lindon Eaves PhD, a leading behavioral geneticist, will provide mentoring in this area. The research plan includes: 1. A detailed review of current instrumentation for assessing preschool anxiety. A pilot study of 60 children aged months, using a multi-informant assessment protocol. Analysis of data on 15, year-old twin pairs to examine the contributions of genes and shared and non-shared environmental factors to young children's anxiety symptoms.

Submission of an R01 application for a longitudinal, genetically-informed study of the development of anxiety disorders in preschool children. This work will make important contributions to the development of prevention and treatment interventions for young children and will contribute to our understanding of the etiology of childhood psychopathology. The data comprise intensive, juvenile and young adult longitudinal, multi-rater child, parent, teacher , interview and questionnaire assessments of psychopathology, environment and psycho-social risk factors in families of like- and unlike-sex adolescent twin pairs and their parents.

Potential covariates and risk factors include: parental psychopathology; pre- and perinatal factors; life-events; home environment; socioeconomic and contextual variables; personality; interactions with peers, siblings and parents. The project will: 1 characterize the impact of age and sex on the contributions of genes, family environment and individual environment on principal mood and behavioral disorders and risk factors through adolescence into young adulthood. Where appropriate, the robustness of findings will be explored to minimize misleading claims and new analytical methods employed to reflect the new generation of questions.

This project focuses on early identification of anxious children and pilot testing of school-based group interventions for anxious youth. Anxiety disorders are among the most prevalent psychiatric disorders in children. These disorders are strongly associated with risk for later developing mood disorders and other psychiatric disorders, academic failure, substance abuse problems, and other significant health problems.

Anxiety disorders are associated with functional impairment and substantial morbidity. Longitudinal studies have demonstrated that untreated anxiety disorders in children may continue for years. For all these reasons, early identification and intervention are critical for preventing anxiety disorders and returning anxious children to the normal developmental trajectory.

This R21 will employ a multiple gating procedure to identify children ages with features or diagnoses of separation anxiety disorder, generalized anxiety disorder, or social phobia. Schools will be randomly assigned to one of three conditions: 1 group cognitive-behavioral therapy CBT for children, 2 group CBT for children plus parent training, or 3 treatment as usual.

Trental 600 mg yan etkileri trental 200mg

Treatment as usual will consist of whatever the school would normally recommend for a child identified as anxious. All children will be followed prospectively with assessments at 3 months and 6 months post-treatment. Outcome measures will evaluate symptom severity, level of functioning, remission of baseline anxiety disorders, and incidence of new anxiety disorders. Data from this study will guide a large-scale school-based investigation of group interventions for anxious youth.

Research and theory on the etiology of these disorders has focused, in part, on individual differences in the intensity of fear behaviors. However, the mechanisms by which individual differences in fear put children at risk for developing behavioral problems have not been fully established.

This proposal focuses on a model that posits the dysregulation of fear behavior as one potential mechanism to the development of internalizing problems.

Historically, research on extremely fearful children has focused on observations during a limited variety of threatening contexts, situations in which most children are expected to show some level of fear. However, extreme fear during a fear-eliciting context may or may not reflect dysregulation. Therefore, the proposed study addresses whether different novel contexts, varying in their level of threat, result in an average pattern of change among all children, and individual patterns of change in the expression of fear-related behaviors. Specifically, the goal of the study is to evaluate two definitions of dysregulated fear behavior: cross-situational consistency in fear behavior and fear behavior in nonthreatening contexts Aim 1.

Participants will be 80, typically developing, month-old children. Children will be observed in 12 situations, and fear behaviors will be assessed during each. Of particular interest is the identification of children who fail to regulate fear behavior based on contextual demands i.

Finally, the validity of the two definitions of dysregulated fear will be evaluated via associations with cortisol and maternal report of behavior problem symptoms, with particular focus on internalizing symptoms Aim 2. These results are expected to further our understanding of the developmental risk factors and etiology of internalizing disorders in children, with particular focus on individual differences in emotion regulation. Better understanding of these risk factors will help to identify appropriate treatment and possible prevention.

Sandra Baker-Morissette to foster her academic and research career development as a clinical scientist in smoking, 34 Anxiety Disorders nicotine dependence and psychiatric comorbidity. Baker-Morissette's career development plan spans 5 years, during which she will continue to work closely with her sponsor, Dr. Gulliver, as well as her co-mentors, Drs.

Statistical consultation will be provided by the Boston University School of Medicine. Her career plan includes individual meetings with each mentor, mentorship team meetings, and coursework in statistical analysis and ethics. Her shortterm goals are to expand upon her theoretical, methodological, and statistical skills needed to become a highly productive clinical scientist and to develop an independent programmatic line of research.

Baker-Morissette's plan should yield sufficient experience as defined by data collection, grant writing, and paper presentations to advance by the close of the award to Associate Professor. Baker-Morissette's overarching ambition is to make a meaningful contribution to the knowledge base on tobacco use and comorbid anxiety disorders across the lifespan.

The proposed study expands on Dr. Baker-Morissette's initial studies of anxiety and tobacco use research by examining the effects of nicotine and mood cue exposure on smoking urge and anxiety in cigarette smokers who have comorbid anxiety disorders. In a between- and within-subjects design, smokers will receive a nicotine 21 mg or placebo patch in a counterbalanced order across two assessment days. During each assessment day, they will engage in a series of imaginal cue exposures that vary in content: smoking plus anxiety cues, smoking cues alone, anxiety cues alone, and neutral cues.

Participants will complete self-report questionnaires prior to and following each exposure, including measures of smoking urge and anxiety. Understanding the effects of nicotine on smoking urge in a psychiatric population is particularly important in light of the difficulty that smokers with psychiatric comorbidity have with quitting smoking. Knowledge of such factors may assist our understanding of conditions that influence the relapse process, as well as the effect of certain cues on smoking urge when individuals are attempting to quit smoking and simultaneously using transdermal nicotine replacement therapy.

In sum, this research will foster the career development of Dr. Baker- Morissette, and ensure the next step of her programmatic research, which has an excellent probabilit3-to increase our understanding of the links between nicotine, negative affect and tobacco use disorder. The two major goals of the current application are the development of innovative new models for basic and clinical Studies 35 research in mood disorders and the intensive scrutiny of 5 novel GSK antidepressant candidates in preclinical and clinical paradigms.

The research component of the proposal is a series of studies investigating the hypothesis that estrogen restrains fear associated behaviors. Clinical data indicates that reproductive hormones fluxes have profound effects on the course of anxiety disorders and depression, but the neurobiological determinants of these clinical observations are not well understood. The specific aims of the research plan are to: 1 study the effects of estrogen on a battery of behavioral tests of anxiety; 2 examine the effects of estrogen on glucocorticoid and stress induced enhancement of fear behaviors; 3 examine the effects of estrogen on extrahypothalamic CRH and glucocorticoid receptors, a neuroendocrine system known to modulate fear and anxiety and 4 define the anatomic sites of estrogen action on fear behaviors.

Fear associated neural circuits involving the amygsala, bed nucleus of the stria terminalis, and medial prefrontal cortex will be studied using local administration of estrogen and estrogen antagonists. The training portion of this proposal consists of basic neuroscience coursework and seminars as well as hands-on instruction in behavioral analysis and functional neuroanatomic techniques. Studies of the effects of estrogen on anxiety related neural systems provides an opportunity for the investigator to expand her area of expertise from clinical neuroendocrinology and clinical psychiatry to behavioral neuroscience where the effects of hormones on brain function can be studied more directly.

This field of investigation is likely to improve understanding and treatment of anxiety and affective disorders, both of which are widely prevalent, chronic public health problems. The biopsychosocial causes of alcoholism are complex; however, the current literature indicates that anxiolysis is prominent in the reinforcing effect of alcohol. Many investigators are currently using animal models to elucidate the biological substrates of anxiogenesis and anxiolysis. These studies now indicate a significant role for the amygdala in mediating these phenomena, and suggest that the amygdala is the most appropriate model system for investigating the physiological substrates of ethanol-mediated anxiolysis.

In spite of this groundwork, few studies have addressed effects of ethanol on amygdala physiology. As ethanol effects are specific for brain regions and neuron types, only a study of direct ethanol effects in the amygdala will provide this informa on. The present proposal will use state-of-the-art electrophysiological techniques to investigate effects of ethanol in the amygdala brain slice preparation. Although ethanol in relevant concentrations likely acts at multiple neuronal sites, it still retains a remarkably high degree of specificity.

The most consistent findings are effects on synaptic transmission and voltage-sensitive ion channels. This proposal will include investigations of interactions between ethanol and voltage-dependent currents, synaptic transmission, and synaptic plasticity. The results of this proposal have potential applications in several areas. By examining physiological effects of alcohol with a specific focus on mechanisms underlying the anxiolytic and anxiogenic actions, this study may direct future clinical studies on causes and treatment of alcoholism.

This study also may elucidate mechanisms involved in development of anxiety disorders and seizure disorders. Finally, the proposed work will provide critical groundwork needed to assess the role of specific neurotransmitters in ethanol-induced anxiolysis and to investigate the long-term effects associated with repeated ethanol use. Their clinical and etiological complexity may obscure efforts to uncover mechanisms and tc discover therapeutic agents against those mechanisms. One common clinical feature that heightens complexity is comorbid anxiety.

Combined anxiety and affective disorder syndromes exacerbate functional morbidity and suffering of patients, but may also present an opportunity to discover shared etiologic factors The candidate for this career development award is an academic psychiatrist at a teaching hospital with a strong historical commitment to medical research.

The candidate has already established a reputation as a clinical specialist in affective disorders and has a research background in the genetics of affective disorder; by the end of the award period he plans to have established firmly a clinical and research direction aimed a comorbid anxiety and affective disorders, with fluency in psychophysiological methods.

The award will Studies 37 facilitate this process by providing the time and resources to pursue further training in psychophysiology, neuroscience, and genetics. The starting points for the proposed research are 1 epidemiological findings that bipolar and panic disorders commonly occur together comorbid risk , 2 symptom provocation studies ir panic disorder that reveal latent panic vulnerability in relatives of panic disorder patients familial risk , and 3 family study results that show both familial and comorbid risk for panic disorder.

The research program proposed here will address further questions about the relationship of panic and bipolar disorders by the use of carbon dioxide inhalation to provoke panic symptoms in study subjects ascertained for genetic linkage study of bipolar disorder.

  • Risk of panic response to carbon dioxide in subjects without prior panic disorder will be analyzed as a function of familial and comorbid risk as compared to the risk in positive and negative control subjects. If there is a specific genetic risk factor for both bipolar and panic disorder in a subset of families, then familial and comorbid risk will interact to produce higher risk of provoked panic than will either risk factor alone. Results of this work will then be applied to ongoing genetic studies of bipolar disorder, and will inform the candidate's further research into affective and anxiety disorder etiology.

    EDDY will focus on depression and diabetes in 10 to 19 year old youth at two ethnically diverse sites: South Carolina and Colorado. This case-cohort will allow investigation of the complex association between diabetes and depression in three major ethnic groups, African American, Hispanic, and Non-Hispanic Whites.

    Diabetes mellitus DM is the third most prevalent severe chronic disease of childhood, and a major cause of morbidity, mortality, and compromised quality of life. Childhood DM is now acknowledged to be a complex and heterogeneous disorder, with increasing rates of type 2 DM. A few smaller studies have found that children with DM are at higher risk for depression and that depressed children with DM may be at increased risk of poor management and complications.

    Existing studies have been small, and restricted to type 1 diabetes.

    We will examine the mutual impact of depression on diabetes management, glucose control, quality of life, and complications, as well as the impact of DM disease burden on the risk for depression. Specifically, we will estimate the prevalence and incidence of depression and related affective and anxiety disorders among youth with DM, and explore the correlates and predictors for depression among children and teens with DM, including parenting, self-efficacy, body image, and self-esteem.

    We will also investigate the impact of depression on diabetes management, clinical course, and complications in both type 1 and type 2 DM, and examine the extent of effective treatment for depression, and the impact of treatment on 38 Anxiety Disorders DM outcomes. Finally, we will explore the pathways involved in the association between DM and co-morbid depression and recurrent depression, with particular attention to disease burden, self-concept, obesity, and parenting.

    A genetic model organism approach will be taken, using the nematode Caenorhabditis elegans. GABAA receptors are the major inhibitory neurotransmitter receptors in the brain, and play important roles in most brain functions. The abundance of GABAA receptors at synapses is an important factor in normal nervous system function, and in the progression of nervous system disease, particularly anxiety disorders. Studies in mammalian systems suggest that receptor abundance is regulated by controlling receptor biosynthesis, trafficking to synapses, and degradation.

    However, results to date have been largely descriptive. We lack an understanding of how these processes occur, and how they may be regulated. Progress has been slowed by the difficulty of perturbing mammalian gene expression, the anatomical complexity of the mammalian nervous system, and the structural heterogeneity of mammalian GABAA receptors. One solution is to take a genetic approach in a simple model organism. The specific aims of this proposal are two-fold: First, the points along the biosynthetic, trafficking, and degradation pathways that control GABAA receptor abundance at synapses will be determined.

    To achieve this aim, these points will be perturbed genetically, and the effects on the regulation of receptor abundance will be determined. Measurements of receptor function using electrophysiology , receptor subcellular localization, and receptor mRNA and protein levels will be performed. Second, the genes that are important at each of these potential regulatory points will be determined.

    This aim will be achieved by forward genetic screening using a functional GFP-tagged receptor. These initial data will form the basis of a substantial future research program to understand how GABAA receptor abundance at synapses is regulated. Because cellular processes are generally well-conserved between C.

    The main difference between these two projects is that the first one studies learned fear while the second one studies innate fear. One disadvantage of innate fear over learned fear is that the underlying brain circuitry is less well understood. Therefore our first aim will be to identify which brain regions are controlling innate fear responses.

    To facilitate that dissection we have chosen to use as a starting point knockout mice that display increased anxiety-like phenotypes in tests of innate fear rather than selected inbred strains. In the knockout strains, the phenotype results from the absence of a single known gene. As a result the phenotype can be further dissected by using tissue-specific ablations of that same gene.

    In contrast, in inbred strains the phenotype is likely to result from the combined effect of many unknown genes which makes it much more difficult to assess the relevant brain regions. Another difference between projects 1A and 1B resides in the nature of the genes that will be identified in these two projects.

    In Project 1A, genes will be identified that are involved in the acute expression of fear in the normal adult brain; in contrast in Project 1B, we will attempt to identify genes that are differentially expressed either during development or in adulthood in the brains of "chronically anxious" mice. Whether these two gene pools are overlapping or not is unknown; however, both gene pools should provide candidates for the genetic determinants of anxiety disorders or anxiety-related traits Projects 2, 3 and 4. The first goal of this project is to identify the brain regions and genes that are involved in innate fear responses.

    We will use knockout strains that rate high or low in tests of innate fear such as the 5-HT1A and the NK1 receptor knockout mice and we will use tissue specific and inducible knockout and rescue strategies to determine which circuits and developmental time periods are responsible for the anxious-like phenotype of these mouse strains. The second goal of this project is to compare these animal models of innate fear to the models of learned fear studied in Project 1A.

    Specifically we will study the behavior of the various knockout and rescue mice in conflict tests and fear conditioning tests to establish whether there is a correlation between these two types of anxiety-related paradigms. These studies parallel the human studies aimed at establishing correlations between neuroticism, behavior in fear conditioning paradigms, and anxiety disorders projects 3 and 4. The third goal of this project will be to identify candidate downstream effector genes of the 5-HT1A or NK1 receptors. ICON Group.
