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 predetermined language-calculation network was limited to the left inferior frontal gyrus, angular gyrus, superior parietal lobule, and the horizontal portion of the intraparietal sulcus. The results were significant to support that there was a pattern of left lateralization for each of these tasks all activating the Perisylvian fissure ...
The opercular cortex surrounding the insula is separated by two anatomical components: the ascending rami of the lateral sulcus and the posterior rami into three different sections of the operculum. [3] Frontal operculum formed by posterior part of the inferior frontal gyrus.
The left frontal operculum region of the prefrontal cortex, or Broca's area, is responsible for expressive language, i.e. language production. The orbitofrontal cortex is concerned with response inhibition, impulse control, and social behaviour.
The same study revealed differences in the anatomical connection patterns between the left and right hemisphere. [4] The circular sulcus of insula (or sulcus of Reil [5]) is a semicircular sulcus or fissure [5] that separates the insula from the neighboring gyri of the operculum [6] in the front, above, and behind.

The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.
Brodmann area 44, or BA44, is part of the frontal cortex in the human brain.Situated just anterior to premotor cortex and on the lateral surface, inferior to BA9.. This area is also known as pars opercularis (of the inferior frontal gyrus), and it refers to a subdivision of the cytoarchitecturally defined frontal region of cerebral cortex.
The primary gustatory cortex (GC) is a brain structure responsible for the perception of taste.It consists of two substructures: the anterior insula on the insular lobe and the frontal operculum on the inferior frontal gyrus of the frontal lobe. [1]
