Abstract:A fundamental trait of intelligent behavior is the ability to respond selectively to stimuli with higher value. Where along the somatosensory hierarchy does information transition from a map of stimulus location to a map of stimulus value? To address this question, we recorded single-unit activity from populations of neurons in somatosensory cortex (S1) and midbrain superior colliculus (SC) in mice conditioned to respond to a positive-valued whisker stimulus and withhold responses using an adjacent, negative-v… Show more
