Research OverviewOur long-term goal is to understand the neural basis for the powerful computations that the cortex performs: in particular, how perception is generated, how behavior is controlled, how the cortex adapts in response to the environment during development, and how changes in cortical function result in neurological and psychiatric disease. With the belief that knowledge of detailed structure is a key to comprehending cortical functions, we focus on delineating the cortical synaptic circuitry to provide a structural basis for the cortical representation and processing of sensory information. In this project, using in vivo whole-cell recording and imaging techniques, and exploiting mouse molecular genetics, we will first determine how different types of sensory-driven synaptic inputs of individual cortical neurons are structured to achieve their specific laminar processing in the adult auditory cortex. Complimentarily, we will exploit functionally-mapped cortical slices to reveal the nature and pattern of individual neuronal connectivity underlying sensory-driven inputs. In addition, we will characterize the structure of functional synaptic circuits in developing auditory cortex. By correlating the specific developmental changes in cortical synaptic circuitry to those in cortical function, we hope to extract synaptic circuitry mechanisms for the maturation of cortical function, and elucidate the determinant structural factors for specific cortical functions. We think that these studies will shed light on synaptic basis of cortical computations, as well as cortical pathologies.
