Marginal Sulcus

The Marginal Sulcus (also known as the Marginal Fissure or Fissure of Rolando) is a significant structure in the human brain. It is a deep groove that separates the frontal lobe and the parietal lobe.

Etymology[edit | edit source]

The Marginal Sulcus is named after the Italian physician and neuroscientist Luigi Rolando, who first described it in the 19th century. The term "sulcus" is derived from the Latin word for "groove" or "furrow".

Anatomy[edit | edit source]

The Marginal Sulcus begins near the midline of the brain, just anterior to the paracentral lobule. It runs laterally and slightly downward, curving around the upper end of the central sulcus. The Marginal Sulcus is part of the larger cerebral cortex, the outer layer of the brain responsible for higher cognitive functions.

Function[edit | edit source]

The Marginal Sulcus plays a crucial role in separating the frontal lobe, which is responsible for decision making, problem-solving, and control of purposeful behaviors, from the parietal lobe, which processes sensory information and is involved in spatial awareness and perception.

Clinical Significance[edit | edit source]

Damage or abnormalities in the Marginal Sulcus can lead to a variety of neurological conditions. For example, a stroke affecting this area can cause motor deficits or sensory loss on the opposite side of the body.
