The goal of the Bruno Lab's research is to understand the neural networks that produce sensory behaviours: how the various layers of the neocortex and thalamic nuclei contribute to sensory perception of the environment, learning, and decision making. Our experiments combine sensory behaviours with intracellular physiology, array recordings, two-photon microscopy, optogenetics, and computational modelling. We focus on the whisker-barrel system, which is one of the main means by which rodents explore their environments.
