parahippokampalisen

The parahippocampal gyrus is a C-shaped convolution on the ventral (inferior) surface of the temporal lobe. It is a key component of the limbic system and plays a significant role in memory formation and retrieval. The parahippocampal gyrus is bordered by the collateral sulcus on its inferior side and the rhinal sulcus on its superior side.

This brain structure is primarily involved in processing and encoding memories. It receives input from various sensory areas and integrates this information to form a cohesive representation of experiences. The parahippocampal gyrus is considered to be crucial for the consolidation of short-term memories into long-term memories.

Damage or dysfunction of the parahippocampal gyrus can lead to significant memory impairments, including anterograde amnesia, the inability to form new memories. It is also implicated in various neurological and psychiatric conditions such as Alzheimer's disease and epilepsy. Functional neuroimaging studies have consistently shown activation of the parahippocampal gyrus during memory-related tasks, further highlighting its central role in mnemonic processes.
