| The term precentral region, or Regio praecentralis, refers to a cytoarchitecturally defined portion of the cerebral cortex that lies immediately rostral to the central sulcus. It occupies caudal portions of the superior frontal gyrus and middle frontal gyrus and the precentral gyrus. It extends into the rostral bank of the central sulcus, though not to the full depth of the sulcus at all points. It consists of the gigantopyramidal area 4 and the agranular frontal area 6. |
