| summary | Uncertainty and doubts are driving exploration of the world. Monitoring uncertainty is indeed a fundamental aspect of normal cognition in primates.
Neurobiological studies only recently considered the role and neural correlates of such monitoring during flexible and adaptive behaviours. It is associated with varied networks of prefrontal cortical areas and with reward-related circuitry linking cortex to the striatum. Yet the precise dynamical recruitment of these cortical networks and their specific contributions to adaptive mechanisms are still unknown.
In this presentation I will show how monitoring decisions and actions under uncertainty undoubtedly involve the midcingulate cortex (MCC) in both human and non-human primates. This concerns using reward values for decision-making, evaluating gains and losses, and tracking uncertainty. I will present investigations on the dynamical interplay between MCC and the lateral prefrontal cortex during adaptation. In particular the dynamics in the two structures suggest a lead of MCC for feedback processing under uncertainty, and for decisions to seek for goal-related information.
Finally I will show that in both human and non-human primates, the function of MCC probably extends to monitoring any information (not just reward) relevant to adaptation, and that this function is processed by specific cortical maps. |
