In human brain anatomy, an operculum, may refer to the frontal, temporal, or parietal operculum, which together cover the insula as the opercula of insula. It can also refer to the occipital operculum, part of the occipital lobe.
Development
Normally, the insular opercula begin to develop between the 20th and the 22nd weeks of pregnancy. At weeks 14 to 16 of fetal development, the insula begins to invaginate from the surface of the immature cerebrum of the brain, until at full term, the opercula completely cover the insula. This process is called opercularization. ==Case reports==
Case reports
Albert Einstein's brain Opinions differ on whether Albert Einstein's brain possessed parietal opercula. Falk, et al. claim that the brain actually did have parietal opercula, while Witelson et al. claim that it did not. Einstein's lower parietal lobe (which is involved in mathematical thought, visuospatial cognition and imagery of movement) was 15% larger than average. ==See also ==
