Temporal lobectomy is the most common type of surgery for people with temporal lobe epilepsy. Damage to the hippocampus and related medial temporal lobe (MTL) structures leads to memory deficits in patients with medial temporal lobe epilepsy (MTLE) [1]. The The temporal lobes are also believed to play an important role in processing affect/emotions, language, and certain aspects of visual perception. Damage to the The medial temporal lobe consists of the hippocampal formation (blue-green) superiorly and the parahippocampal gyrus inferiorly. Medial temporal lobe (MTL) damage in humans is typically thought to produce a circumscribed impairment in the acquisition of new enduring memories, but recent reports have documented deficits even in short-term maintenance.

The first type of TLE is mesial temporal lobe epilepsy (MTLE) which involves the medial temporal lobe, including the hypothalamus and surrounding areas. The parieto At least three anatomical entities qualify as components of the medial temporal lobe. One of the four major lobes of the cerebral cortex in the brain.. Memory Loss. 6. The dominant temporal lobe, which is the left side in most people, is involved in understanding language and learning and remembering verbal information. The temporal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The medial side of the temporal lobe includes regions concerned with olfaction (the uncus and nearby cortex) and semantic memory (the hippocampal formation). The hippocampus is a structure in the temporal lobe that is responsible for forming emotional, long-term memories.
