Collateral eminence

Collateral eminence is a structure found in the brain. It is a part of the limbic system, specifically located in the hippocampus. The collateral eminence is situated in the ventromedial part of the temporal lobe, adjacent to the amygdala and the parahippocampal gyrus.

Anatomy

The collateral eminence is a prominent elevation in the floor of the collateral sulcus. It is formed by the fusiform gyrus and the parahippocampal gyrus. The collateral eminence is located in the medial part of the temporal lobe, and it is separated from the hippocampal formation by the rhinal sulcus.

Function

The collateral eminence is involved in various cognitive functions, including memory and emotion. It is also implicated in several neurological and psychiatric disorders, such as Alzheimer's disease, schizophrenia, and epilepsy.

Clinical significance

Due to its location and involvement in various cognitive functions, damage to the collateral eminence can lead to a variety of neurological and psychiatric disorders. For example, in Alzheimer's disease, the collateral eminence is one of the first areas to show signs of neurodegeneration. Similarly, in schizophrenia, abnormalities in the collateral eminence have been associated with cognitive deficits.
