How do the neural networks of the cerebral cortex mediate sensation? Sensory information from the environment—for touch, sight, hearing, taste, and smell—is encoded by cascades of excitation among neurons. As excitation spreads, these circuits transform the information into new representations that drive our behaviors. Neural processing underlies not only sensation but also working memory, decision making, and action planning and is inseparable from the circuits transforming that information. My laboratory has been conducting anatomical, physiological, imaging, and behavioral experiments to investigate the workings of sensory circuits, specifically in barrel cortex, which mediates rodents’ sense of touch with their large facial whiskers. We employ a variety of methods in our experiments, ranging from in vivo intracellular and extracellular recording, two-photon microscopy, optogenetics, to computational modeling. Recently, our laboratory began focusing on the role of cortical layers in specific behaviors.
