Optically probing the neural basis of sensory perception
He will discuss three recent advances in his lab. First, Ihe will describe a microcircuit in the mouse visual cortex that dynamically matches the integrative mode of cortical networks to perceptual demands. Second, exploiting the discrete architecture of the mouse somatosensory barrel cortex, he will show how barrel cortex neurons encode a sparse, distributed code of higher order tactile features underlying shape perception. Third, he will highlight their recent technical advances for cracking neural codes of sensory perception with multiphoton optogenetics.
