superior precentral dimple
Acronym: sprd
The term superior precentral dimple refers to a superficial feature of the frontal lobe in the macaque. It is a short horizontal depression located just anterior to the central sulcus near its dorsal margin ( Bonin-1947 ). Though sometimes referred to as the superior precentral sulcus ( Szabo-1984 ), it is probably not homologous to the superior precentral sulcus of the human. (See arcuate sulcus of the macaque.)
     An equivalent feature is not seen in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).
