Document Summary
Schema control units (rep of responses): correspond to explicit mvmts/activation of long term rep that lead to purposeful behaviors. Contention scheduling: manages schemas for automatic/familiar actions (fast, passive: prevents competing actions and ensures that we act coherently. Mfc (esp acc) ** as a monitoring system. Acc -- limbic system -- helping to modulate autonomic responses in painful/threatening situations. Mfc -- when task becomes more difficult; monitoring demands high. How does mfc monitor processing in cognitive control networks. Dti studies: 11 subregions in acc -- strong connectivity with ofc, vstriatum, Pmc : mfc = * influence decision making, goal-oriented behavior, motor control. Mfc - upper rung of hierarchy: coordinate activity across attentional systems. Selective attention: local changes in regions: attending to motion -- blood flow in lateral prestriate cortex, color -- flow to medial regions. Divided attention : higher-level attentional system: most in acc, novel conditions, more difficult tasks.
