The operculum, defined as the cortex adjacent to the insula, is a large structure encompassing three lobes, with a recognized role in a variety of neurologic and psychiatric conditions.
The operculum can be divided into frontal, parietal and temporal regions, after the lobes of which they form a part. The part of the operculum on the precentral and postcentral gyri, on either side of the central sulcus (or “Rolandic fissure”), is known as the Rolandic operculum.
