Macro-neocortical dynamics, cognition, and EEG

A conceptual framework for neocortical dynamic behavior is proposed to embrace brain theories applied to different experimental designs, spatial scales, and brain states. Neocortical dynamics and correlated behavioral/cognitive brain states are viewed as distinct, but interacting local (regionally specific) processes and globally coherent dynamics. Global processes can facilitate synchronous activity in remote cell groups (top down) which function simultaneously at several different spatial scales. At the same time, local processes may help drive (bottom up) macroscopic global dynamics observed with EEG (or MEG).
