Subcallosal gyrus

Subcallosal Gyrus is a small region of the brain located in the medial part of the brain's cerebral hemisphere. It is part of the limbic system, a complex system of nerves and networks in the brain that controls basic emotions and drives.

Etymology

The term "Subcallosal Gyrus" is derived from Latin. "Sub" means under, "callosum" refers to the corpus callosum, a broad band of nerve fibers joining the two hemispheres of the brain, and "gyrus" means a ridge on the cerebral cortex.

Anatomy

The Subcallosal Gyrus is located below the corpus callosum, the largest white matter structure in the brain that allows communication between the left and right cerebral hemispheres. It is part of the limbic lobe and is situated between the cingulate gyrus and the paraterminal gyrus.

Function

The Subcallosal Gyrus is involved in several functions of the brain, including emotion formation and processing, learning, and memory. It is also associated with the regulation of the endocrine system and autonomic functions.

Clinical Significance

Alterations in the Subcallosal Gyrus have been associated with several psychiatric disorders, including depression, schizophrenia, and bipolar disorder. It is also a target for deep brain stimulation in treatment-resistant depression.
