This graphic summarizes the anatomy of non-primary cortex in primates while presenting a hypothesis about the functional roles that emerge from these neuroanatomical circuits. While primary cortical regions contain anatomical specialization, non-primary regions seem to have a common functional blueprint. We propose neurons in the cerebral cortex are organized into 4 functional systems, involving 8 pyramidal neuron types, 3 different thalamocortical projections, allocortical projections, and various subcortical projections. We emphasize non-primary cortical systems because they derive from the six-layered homotypical isocortex which is the largest part of the human brain. We focus on the literature from primates because it is most similar to the human brain. This neuroanatomical review is available in three forms: print, an interactive web-site, and an interactive iPhone/iPad application. We hope our novel application of new media will facilitate rapid review of references by placing them in a functional and spatial context.
