Synchronization and cooperative interaction in brain activity.

A conception is advanced according to which synchronization and the cooperative interaction of plastic processes at the level of the individual cell and of cell units of varying degrees of complexity form a principle of cerebral integration. The triggering and unfolding of plastic reorganizations which take place with the participation of motivational-emotional structures are realized through the mechanism of alteration of cell excitability. These influences are widely distributed throughout the cerebral cortex, but are selective in relation to the current need of the organism.
