Abstract
Anatomical evidence suggests that planning and execution of adaptive behaviors in mammals may involve coordinated neuronal activity throughout the neocortex. To investigate this previously-unapproachable hypothesis, in collaboration with others, I developed a set of optical tools for probing fast neuronal activity across many cortical regions simultaneously. One of these methods—COSMOS—allows synchronous recording at 30 Hz from over a thousand near-cellular resolution neuronal sources distributed throughout the entire dorsal neocortex of awake mice. We applied these tools to make three discoveries. First, we found global cortical representations of goal-directed task engagement, with cell-type specific dynamics. Second, we identified neuronal population representations spanning dorsal neocortex that precisely encode ongoing and planned motor actions. Third, we discovered a localized neuronal rhythm underlying dissociation, a mysterious altered behavioral state in which normally-integrated cognitive processes—such as those linking the sense of self to body-position and action—become selectively disconnected. Together, these results illuminate how circuits throughout the brain of behaving mammals function as a coupled system—and the consequences that can arise when they decouple.
