Brain Anatomy and Structures

The video tutorial provides an in-depth look at the cerebral hemisphere's medial surface, focusing on the corpus callosum and its four parts: rostrum, genu, body, and splenium. It describes the longest sulcus, the cingulate sulcus, and its relation to surrounding gyri. The tutorial also covers the frontal, parietal, and occipital lobes, highlighting key features like the parieto-occipital fissure and calcarine fissure. Additionally, it explores the temporal lobe, including the uncus and parahippocampal gyrus, and introduces the fusiform gyrus, emphasizing its role as a collective structure of medial and lateral occipital-temporal gyri.
