英文摘要
Project Summary
Flexible behavior is central to virtually all cognitive and social abilities. Recent technical advances have opened an
unprecedented opportunity to comprehensively dissect the neural circuit mechanisms of this ability across multiple
brain areas in freely behaving animals. This proposal focuses on the cerebellum, a structure that is a major site of
pathology in autism spectrum disorder. Damage to the cerebellum at birth leads to a 36fold increase in the risk of
autism, and this region is also a principal site for coexpression of autism risk genes. Thus cerebellar
development may act as an intermediate mechanistic step in transducing inherited autism risk into
neurodevelopmental phenotypes. In this project, a multidisciplinary team of leading experts proposes to
investigate the neural basis of this disorder using advanced technologies, including unbiased automatic
classification of behavior, largescale cellularresolution imaging in behaving rodents, mouse genetic models for
autism, and manipulation of neural activity in specific cerebellar areas and cell types. In genetic mouse models of
autism, the researchers will identify modes of behavior based on physical poses, and relate these modes to
classical behavioral tests, such as eyeblink conditioning, and to cerebellar circuit dysfunction. In adult wildtype
and autism model mice, the researchers will use optogenetic methods to perturb specific cerebellar lobules while
quantifying the effects on behavioral dynamics and learning. In juvenile model mice, the researchers will use
chemogenetic methods to identify longlasting patterns of behavioral disruption and relate these patterns across
behaviors to build a quantitative map of these perturbations. In addition, they will use in vivo dendritic imaging to
evaluate the influences of cerebellar perturbation on neocortical neuron structure. All of these results will inform
modeling of cerebellarneocortical interactions to better understand how these differently wired regions interact
during learning and development. The longterm goal of this project is to arrive at a chain of explanation, centered
on principles of convergent neuroscience, to understand causal mechanisms of neurodevelopmental disorders.
This project will join genetics with circuit function, local cerebellar anatomy with behavioral outcomes, and
classical behavioral tests with modern unbiased methods. This project is expected to produce an accurate and
detailed understanding of cerebellar contributions to normal and aberrant neurodevelopment. In addition, the
proposed research will enable researchers to generate and test a variety of hypotheses about the neural basis of
flexible behavior. Taken together, these achievements will represent a crucial step toward a mechanistic
understanding of how the brain develops its complex ability to respond flexibly to the environment, from birth to
adulthood.
