| The term agranular frontal area 6, or Area frontalis agranularis, refers to a subdivision of the cytoarchitecturally defined precentral region of cerebral cortex. In the human it is located primarily in the caudal portions of the superior frontal gyrus and the middle frontal gyrus and the rostral portions of the precentral gyrus not occupied by the gigantopyramidal area 4. It extends from the cingulate sulcus on the medial aspect of the hemisphere to the lateral sulcus on the lateral aspect. Cytoarchitecturally it is bounded rostrally by the frontal region and caudally by the gigantopyramidal area 4. |
