Calcium Imaging

Tao, Huizhong W.

Professor of Physiology and Neuroscience

My lab studies how the mouse brain processes visual information and transforms it into behavior. Our research focuses on identifying the neural circuits involved in visual perception and how these circuits drive visually guided actions. We use a combination of techniques—including electrophysiology to record neural activity, microendoscopic calcium imaging to monitor populations of neurons in freely moving animals, and both optogenetics and chemogenetics to precisely manipulate specific circuit components. By integrating these approaches, we aim to understand how visual signals are encoded, transmitted, and used to guide behavior at the level of individual neurons and larger networks.

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.
