Cerebral fissure

Cerebral Fissure

A cerebral fissure is a deep groove in the brain's surface, separating different regions of the brain. These fissures are a significant part of the brain's physical structure and play a crucial role in its function.

Overview

The brain is divided into several lobes, each responsible for different functions. These lobes are separated by cerebral fissures. The three main cerebral fissures are the longitudinal fissure, the central sulcus (also known as the fissure of Rolando), and the lateral sulcus (also known as the Sylvian fissure).

Longitudinal Fissure

The longitudinal fissure is the most prominent cerebral fissure. It separates the two cerebral hemispheres, the left and the right. Each hemisphere controls the opposite side of the body and is responsible for different cognitive functions.

Central Sulcus

The central sulcus, or the fissure of Rolando, separates the frontal lobe from the parietal lobe. This fissure is crucial for distinguishing between motor and sensory functions of the brain.

Lateral Sulcus

The lateral sulcus, or the Sylvian fissure, separates the temporal lobe from the frontal and parietal lobes. This fissure is associated with auditory processing and language comprehension.

Clinical Significance

Abnormalities or damage to the cerebral fissures can lead to various neurological disorders. For instance, a stroke can cause damage to the area around the central sulcus, leading to motor or sensory deficits. Similarly, damage to the lateral sulcus can affect language comprehension and auditory processing.
