Collateral fissure

Collateral Fissure

The Collateral Fissure is a neuroanatomical structure found in the brain. It is a deep groove that separates the parahippocampal gyrus from the lingual gyrus in the temporal lobe and occipital lobe respectively.

Anatomy

The Collateral Fissure begins near the occipital pole and extends forward to the temporal pole. It is located on the medial surface of the cerebral hemisphere, running parallel to and above the rhinal fissure.

Function

The exact function of the Collateral Fissure is not fully understood. However, it is known to be involved in the separation of the parahippocampal gyrus and the lingual gyrus, which are involved in memory and visual processing respectively.

Clinical Significance

Abnormalities or damage to the Collateral Fissure may be associated with certain neurological conditions, such as epilepsy and Alzheimer's disease. Further research is needed to fully understand the role of the Collateral Fissure in these conditions.
