Abstract
The shape of the inferior horn of the lateral ventricle has been investigated in 100 (50right and 50 left) human brain hemispheres which were fixed in 40% formaldehyde solution and cut frontally. It has been found that the shape of the inferior horn depends on the course and depth of the collateral and occipitotemporal sulci. In most cases a part from two main ventricular surfaces: The hippocampal and superolateral, there is one surface more, either the inferior - collateral eminence (Type I - 97% of cases in the posterior part of the inferior horn, 49%- in the middle and 42%- in the anterior part) or the inferolateral, adjacent to the occipitotemporal sulcus ( Type II- 0%, 26% and 35%, respectively). In a few cases both collateral eminence and inferolateral surfaces were present (Type III- 3% , 2% and 6% respectively). In type IV neither collateral eminence nor the inferolateral surface appeared (0%, 23%, 17% respectively). The authors suggest to designate the inferolateral surface, not mentioned in the literature, as the occipitotemporal eminence (of the inferior horn).
