GENERAL HISTOLOGY

Detailed explanation-1: -The lateral fissure (Sylvian fissure) is a laterally located horizontal fissure and separates the temporal lobe from the frontal and parietal lobe. The parietal lobe is posterior to the central sulcus and anterior to the parieto-occipital sulcus. This lobe controls perception and sensation.

Detailed explanation-2: -The frontal lobe is separated from the parietal lobe by a space called the central sulcus, and from the temporal lobe by the lateral sulcus. The frontal lobe is generally where higher executive functions including emotional regulation, planning, reasoning and problem solving occur.

Detailed explanation-3: -The Rolandic Sulcus: The Rolandic sulcus, also called Rolando or the central sulcus, is a very important sulcus because it delimits the boundary between motor and the sensory cortices, as well as the boundary between the frontal and parietal lobes.

Detailed explanation-4: -Gross anatomy The central sulcus separates the frontal lobe from the parietal lobe, and more specifically separates the primary motor cortex anteriorly from the primary somatosensory cortex posteriorly 1.

Detailed explanation-5: -The cerebral cortex is divided into two halves, or hemispheres. It is covered with ridges (gyri) and folds (sulci). The two halves join at a large, deep sulcus (the interhemispheric fissure, AKA the medial longitudinal fissure) that runs from the front of the head to the back.
