The most common symptom of inferior temporal lobe damage is visual agnosia, which involves impairment in the identification of familiar objects. Another less common type of inferior temporal lobe damage is prosopagnosia which is an impairment in the recognition of faces and distinction of unique individual facial features. [20]
Temporal lobe epilepsy is the most common focal onset epilepsy, and 80% of temporal lobe epilepsy is mesial (medial) temporal lobe epilepsy, temporal lobe epilepsy arising from the inner part of the temporal lobe that may involve the hippocampus, parahippocampal gyrus or amygdala.
Damage to the inferior left temporal lobe, which is shown in green, is associated with TSA. Transcortical sensory aphasia is caused by lesions in the inferior left temporal lobe of the brain located near Wernicke's area, and is usually due to minor hemorrhage or contusion in the temporal lobe, or infarcts of the left posterior cerebral artery (PCA). [4]
Seizures in temporal lobe epilepsy can affect the normal development of new neurons and can cause tissue damage. Hippocampal sclerosis including Ammon's horn sclerosis that is specific to the mesial temporal lobe, is the most common type of such tissue damage.
Molaison's chief complaint was the persistence of severe seizures and therefore had a bilateral lobectomy, with both his medial temporal lobes removed. As a result, Molaison had bilateral damage to both the hippocampal formation and the perirhinal cortex. Molaison had average intelligence and perceptual ability, and a decent vocabulary.
Klüver–Bucy syndrome is a syndrome resulting from lesions of the medial temporal lobe, particularly Brodmann area 38, [1] causing compulsive eating, hypersexuality, a compulsive need to insert inappropriate objects in the mouth (hyperorality), visual agnosia, and docility.
It is traditionally thought to reside in Brodmann area 22, located in the superior temporal gyrus in the dominant cerebral hemisphere, which is the left hemisphere in about 95% of right-handed individuals and 70% of left-handed individuals. [1] Damage caused to Wernicke's area results in receptive, fluent aphasia. This means that the person ...
Implications of Cochrane's neuropathology have shown that damage to specific regions of the brain is associated with different forms of memory loss. As a result of damage to Cochrane's medial temporal lobe, specifically his hippocampus, research suggests that this area functions in processing episodic memory. However, damage to this area has ...
