In human brain anatomy, an operculum (Latin, meaning "little lid") (pl.: opercula), may refer to the frontal, temporal, or parietal operculum, which together cover the insula as the opercula of insula.[1] It can also refer to the occipital operculum, part of the occipital lobe.
The insular lobe is a portion of the cerebral cortex that has invaginated to lie deep within the lateral sulcus. It sits like an island (the meaning of insular) almost surrounded by the groove of the circular sulcus and covered over and obscured by the insular opercula.
A part of the parietal lobe, the frontoparietal operculum, covers the upper part of the insular lobe from the front to the back.[2] The opercula lie on the precentral and postcentral gyri (on either side of the central sulcus).[3] The part of the parietal operculum that forms the ceiling of the lateral sulcus functions as the secondary somatosensory cortex.
