Research Interests

The Levitt laboratory aims to understand the physiological properties and anatomical connections of neurons in visual areas of mammalian cerebral cortex. The ultimate goal of this work is to understand visual perception in terms of its underlying neural substrates. We now know that there are a number of distinct areas of mammalian cerebral cortex with visual functions, yet we do not know why there are so many visual areas, or indeed how single neurons in any area come to have the functional properties that they do. 

Much of our work focuses on characterizing the organization and postnatal development of neuroanatomical circuits linking different areas of mammalian cerebral cortex. We also have an interest in whether there are ultrastructural differences among neurons contributing to different circuits in visual cortex. Parallel electrophysiological studies aim to characterize the responses of single neurons in visual cortex to visual stimuli; understanding differences among areas will clarify the perceptual abilities mediated by those areas. To address these questions, we employ both electrophysiological recording as well as neuroanatomical techniques; these allow one to study not only the physiological properties of brain cells, but also the underlying structural basis for how such functional properties are constructed by the brain.
