英文摘要
PROJECT SUMMARY
Anxiety disorders, as a group, are the most common mental illnesses in the US, affecting about 25% of ado-
lescents and 18% of adults. Symptoms typically begin in childhood or adolescence. A crucial gap in studies of
anxiety is the lack of empirical data linking pediatric anxiety to abnormal brain development. This four-year K01
application presents a program for research and training that will support the applicant on a path towards
becoming an NIH-funded independent investigator, focused on studying the neural correlates of fear generali-
zation in youth with pathological anxiety using interdisciplinary approaches (affective neuroscience, multimodal
neuroimaging, and computational methods). The training plan builds on the candidate’s previous training and
experience, and capitalizes on a mentorship team and a research environment to foster development of the
candidate’s expertise in (1) the phenomenology of anxiety disorders;; (2) patient-oriented, translational and
developmental neuroscience of anxiety;; (3) advanced computational neuroimaging;; and (4) responsible and
ethical conduct in scientific research in vulnerable individuals. The research project will investigate fear gener-
alization behavior and its relationship with vmPFC (ventromedial prefrontal cortex) function and corticolimbic
connectivity in healthy youth (Aim #1), and investigate fear over-generalization behavior and its relationship
with vmPFC function and corticolimbic connectivity in youth with pathological anxiety (Aim #2). We hypothesize
that childhood anxiety involves fear over-generalization and that fear over-generalization involves abnormal
function and connectivity of the corticolimbic system. To test these hypotheses, we will use a fear generaliza-
tion fMRI task and multimodal MRI (structural, diffusion, and functional MRI) in healthy youth without anxiety
(n= 25) as well as in youth with pathological anxiety across a spectrum of severity (i.e., those with subthreshold
anxiety [n=25] and those with any DSM-5 anxiety disorder [n=25]). Successful completion of this study will
provide cross-sectional evidence of the association of pediatric anxiety with fear generalization behavior,
vmPFC function, and corticolimbic system connectivity. The multiple units of analysis will help elucidate brain-
behavior relationships underlying fear generalization. These data along with the research expertise developed
through this K01 award will support a future R01 application to track over time the developmental trajectories of
fear generalization and pathological anxiety in youth. The ultimate goal of this line of research is to develop
neurobehavioral markers to determine when and where to intervene in anxiety disorders (NIMH Strategic
Objective 2) and to promote preventive therapeutic interventions to youth with pathological anxiety (NIMH
Strategic Objective 3).
