Abstract
A hypothesis is proposed that neocortex is constructed from structural neuronal modules (columns and rings). Each module is considered as unit for cortical sensorimotor integration. Complex functional relationships between modules can be arranged by intracortical inhibition participation. High pronounced neocortical plasticity ensures the process of continous formation of various diminating operative constellations comprizing stable neuronal modules whose component structure and distributive characteristic are determined by the dominant motivation and the central motor program.
