'''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==
==Subcallosal gyrus==
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.  
The '''subcallosal gyrus''' is a region of the brain located in the [[limbic system]], which is involved in various functions including emotion, behavior, and long-term memory. It is situated beneath the [[corpus callosum]], a thick band of nerve fibers that connects the left and right cerebral hemispheres.

==Anatomy==
==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]].  
The subcallosal gyrus is part of the [[cingulate cortex]], which is a component of the limbic system. It is located anterior to the [[parahippocampal gyrus]] and inferior to the [[cingulate gyrus]]. The subcallosal gyrus is continuous with the [[paraterminal gyrus]] and is bordered by the [[septal area]].


==Function==
==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.
The subcallosal gyrus plays a role in the regulation of emotional responses. It is involved in the processing of emotions and has been implicated in mood disorders such as [[depression]]. The subcallosal gyrus is thought to be part of a network that includes the [[amygdala]], [[hippocampus]], and [[prefrontal cortex]], which together contribute to emotional regulation and decision-making.


==Clinical Significance==
==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.
Abnormalities in the subcallosal gyrus have been associated with various psychiatric conditions. For instance, changes in the volume and activity of this region have been observed in patients with major depressive disorder. It is also a target for [[deep brain stimulation]] in treatment-resistant depression, where electrical impulses are used to modulate the activity of this brain region.

Part of the brain located in the limbic system



Subcallosal gyrus[edit]

The subcallosal gyrus is a region of the brain located in the limbic system, which is involved in various functions including emotion, behavior, and long-term memory. It is situated beneath the corpus callosum, a thick band of nerve fibers that connects the left and right cerebral hemispheres.

Diagram of the brain showing the location of the subcallosal gyrus.

Anatomy[edit]

The subcallosal gyrus is part of the cingulate cortex, which is a component of the limbic system. It is located anterior to the parahippocampal gyrus and inferior to the cingulate gyrus. The subcallosal gyrus is continuous with the paraterminal gyrus and is bordered by the septal area.

Function[edit]

The subcallosal gyrus plays a role in the regulation of emotional responses. It is involved in the processing of emotions and has been implicated in mood disorders such as depression. The subcallosal gyrus is thought to be part of a network that includes the amygdala, hippocampus, and prefrontal cortex, which together contribute to emotional regulation and decision-making.

Clinical significance[edit]

Abnormalities in the subcallosal gyrus have been associated with various psychiatric conditions. For instance, changes in the volume and activity of this region have been observed in patients with major depressive disorder. It is also a target for deep brain stimulation in treatment-resistant depression, where electrical impulses are used to modulate the activity of this brain region.
