parietal operculum
Acronym: pao
The term parietal operculum refers to the part of the parietal lobe that overlies the caudal portion of the insula in primates. It is defined by dissection. The posterior one-third of the superior limiting sulcus separates it from the insula deep in the lateral fissure. It is the part of the superior bank of the lateral fissure that extends from the plane of the central sulcus caudally to the end of the insula. In the human it is composed of the ventrolateral lips of the postcentral gyrus and the supramarginal gyrus, which overlie the posterior insula ( Mai-2004; Schiebler-1999 ). In the macaque only the postcentral gyrus is involved. The parietal operculum together with the frontal operculum constitute the frontoparietal operculum ( Martin-2000 ). It is not found in rodents.
