PARACENTRAL FISSURE Meaning and Definition

1. The paracentral fissure, also known as the Rolandic fissure or central sulcus, is a prominent anatomical feature found in the human brain that separates the frontal and parietal lobes. It is one of the major fissures that divide the cerebral cortex, the outer layer of the brain responsible for higher cognitive functions.

   Located on the lateral surface of the brain, the paracentral fissure runs in an anteroposterior direction and generally extends horizontally across the hemisphere, connecting the superior and inferior borders of the brain. It starts from the longitudinal fissure, which divides the brain into left and right hemispheres, and terminates near the medial surface.

   The paracentral fissure plays a crucial role in organizing and identifying the regions of the brain. It separates the primary motor cortex, responsible for voluntary movement initiation, from the primary sensory cortex, involved in processing sensory information from various parts of the body. This fissure serves as a landmark for various brain regions, enabling neuroscientists and clinicians to locate and study specific areas of the brain during research or surgical procedures.

   Furthermore, damage or abnormalities in the paracentral fissure can have significant implications on motor and sensory functions, leading to conditions such as paralysis, loss of sensation, or language disorders. Understanding the role and structure of the paracentral fissure is essential for comprehending the intricate workings of the human brain and its impact on behavior and cognition.

2. A curved fissure on the mesal surface of the cerebral hemisphere, bounding the p. gyrus and separating it from the precuneus and the callosal gyrus.
