A system moder of the primate neocortex

Experimental evidence has shown that the primate neocortex consists in the main of a set of cortical regions which form a perception hierarchy, an act ion hierarchy and connections between them. We develop a computational arch itecture for the brain in which each cortical region is represented by a co mputational module with processing and storage abilities. Modules are inter connected according to the connectivity of the corresponding cortical regio ns. We explain our computational principles for designing such a hierarchic al and parallel computing system, and report on results obtained with an im plementation of this causal functioning model of the brain.
