Temporal Lobe
Temporal lobe is one of the four lobes of the Cerebral Cortex of Brain. It is located below the lateral fissure at the lower part of the brain, both on left and right side. This lobe is basically associated with processing sensory input, visual and auditory perception, language skills, long term memory and emotional responses.

Temporal Lobe
COMPONENTS
- Amygdala
- Primary auditory area
- Secondary auditory area
- Hippocampus
- Parahippocampal cortex
- Wernicke's area
BLOOD SUPPLY
This lobe receives the arterial blood supply from the cortical branches of:
- Middle cerebral artery, which is direct and largest branch of internal carotid artery
- Posterior cerebral artery, which is a branch of basilar artery
FUNCTIONS
- Amygdala is concerned with converting short-term memory into long-term memory
- Hippocampus is associated with keeping things into long-term memory
- Visual area is concerned with interpretation of visual stimuli
- Primary auditory area is associated with hearing, a primary function
- Secondary auditory area interprets the meaning of auditory stimuli
- Wernicke’s area is meant for language skills and comprehension
- In addition, our emotional responses are also associated with temporal lobe
CLINICAL IMPORTANCE
Any trauma to the brain can cause damage to the temporal lobe which will be represented as:
- Hearing loss and problem in interpretation of the auditory stimuli
- Problems in perceiving visual input
- Difficulty in comprehension of language
- Unable to organize the verbal material
- Prominent change in sexual life and behaviour towards it
- Personality changes
- Loss of long-term memory
