area 4 of Brodmann (human)
Acronym: 4
The term area 4 of Brodmann (human) refers to a subdivision of the cytoarchitecturally defined precentral region of cerebral cortex. In the human it is located in the precentral gyrus. Cytoarchitecturally the caudal boundary with the area 3 of Brodmann (human) does not coincide precisely with the floor of the central sulcus but lies variably in the banks of the postcentral gyrus and the precentral gyrus. The area also does not extend in all cases to the cingulate sulcus medially or to the end of the central sulcus ventrolaterally. It is bounded rostrally by the area 6 of Brodmann (human) ( Brodmann-1909 ).

Also known as: Brodmann's area 4
