Abstract:The history of stimuli and rewards in the recent past drives an automatic form of attention in animals and humans in which attentional priority is given to previously rewarded stimuli. The neurobiological basis for this form of attention is unknown. In a novel whisker touch detection task, we show that mice flexibly shift attention between specific whiskers, based on this recent history of stimulus-reward association. 2-photon calcium imaging and spike recordings revealed a robust neurobiological correlate in … Show more
