Abstract
The insular cortex, a crucial brain region hidden within the Sylvian fissure, and the Sylvian fissure itself are vital neuroanatomical structures with significant clinical relevance. This cadaveric study investigated the regional anatomy of the insula and Sylvian fissure, specifically exploring the correlation between the anteroposterior length of the insular cortex and the length of the Sylvian fissure on the lateral brain surface. We meticulously dissected and measured 58 insulae and 58 Sylvian fissures from 29 human cadaveric brains obtained from the Department of Anatomy, Gandhi Medical College, Bhopal (M.P.). Our findings revealed a positive correlation between these two linear measurements. Given the known asymmetry and variations of the insular cortex and its intricate relationship with the Sylvian fissure, this study underscores the high clinical and surgical importance of this anatomical region. The detailed morphometric data obtained is expected to provide valuable insights for neuroanatomists, neurosurgeons, neurophysicians, neuroradiologists, and psychiatrists, potentially aiding in surgical planning, understanding neurological disorders, and interpreting neuroimaging.
