====== Operculum ====== {{ ::operculum.png?400|}} 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. ---- [[Frontal operculum]] ---- see [[Pars opercularis]]. see [[Operculum glioma]]. ===== Function ===== see [[Operculum Function]].
