How do developmental and genetic programs build brain circuits for complex behavior? My lab investigates this question by integrating developmental neuroscience, molecular genetics, and multi-scale circuit mapping to study cortical sensorimotor circuits underlying goal-directed actions and perception. Using interdisciplinary approaches, such as gene knockin mouse lines and single cell profiling, we examine how neuronal identity and connectivity emerge during development. Our goal is to uncover the molecular and developmental logic of circuit assembly in neurotypical development and how the key building blocks that make up the circuits—cell types—are disrupted in neurodevelopmental disorders. We hypothesize that a temporal patterning program during pregnancy specifies neuron subtype and wiring, shaping sensorimotor function in the mature brain.

Our research is designed to better understand the fundamental changes in the inner ear that underlie progressive hearing loss and to develop novel techniques to treat this problem before it leads to a severe disability. We strive to understand the biological mechanisms of hearing loss and then translate this knowledge to directly and rapidly improve the care of patients with hearing loss.

The peripheral auditory system transforms air-borne pressure waves into neural impulses that are interpreted by the brain as sound and speech. The cochlea of the inner ear is a snail-shaped electro-hydromechanical signal amplifier, frequency analyzer, and transducer with an astounding constellation of performance characteristics, including sensitivity to sub-atomic displacements with microsecond mechanical response times; wideband operation spanning three orders-of magnitude in frequency; and an input dynamic range of 120 dB, corresponding to a million-million-fold change in signal energy. All of this is achieved not with the latest silicon technology but by self-maintaining biological tissue, most of which is salty water. How does the ear do it? To address this question, we exploit the ear's curious ability to make sound while listening to sound.
Zhang, Li
Professor of Physiology and Neuroscience
As systems neuroscientists, we aim to decipher brain circuits to understand how perception and behavior arise, how the brain adapts to a dynamic environment, and how circuit dysfunction contributes to neurological and psychiatric disorders. We focus on resolving neural architecture—the wiring of neurons that underlies brain function. Technical innovation is central to our approach. We have developed molecular, genetic, electrophysiological, and imaging tools to study circuits supporting both local computation and behavior. Our research integrates in vivo and in vitro electrophysiology, two-photon calcium imaging, neural modeling, anatomical tracing, and optogenetics to build a comprehensive understanding of cell-type-specific circuit mechanisms.
