In terms of its cytoarchitecture, it is bounded rostrally by the supramarginal area 40 ( H ), dorsally and caudally by the peristriate area 19, and ventrally by the occipitotemporal area 37 ( H ) ( Brodmann-1909 ).

Dum and Strick hypothesized on the basis of cytoarchitecture and connections to the spinal cord that the portion of SMA in the cingulate sulcus, on the medial part of the hemisphere, can be split into three separate areas, the cingulate motor areas.

Defined on the basis of cytoarchitecture, it is more similar to the presubiculum than to the entorhinal area ( Zilles, 1990 ), however electrophysiological evidence suggests a similarity with the entorhinal cortex ( Funahashi and Stewart, 1997; Glasgow & Chapman, 2007 ).

The premotor cortex has been divided into finer subregions on the basis of cytoarchitecture ( the appearance of the cortex under a microscope ), cytohistochemistry ( the manner in which the cortex appears when stained by various chemical substances ), anatomical connectivity to other brain areas, and physiological properties.
