Temporal
Function Lesion
General Integrative functions: Left temporal:
- Verbal memory disturbance
Auditory and visual perception - Processing of speech sounds
- Temporal association cortex - Personality disturbances
- Perception, identification and categorization
- Necessitates detailed and focused perception Right temporal:
- Nonverbal memory
Memory (LTM for sensory input) - Processing music
- (medial area + role of hippocampus) - Personality disturbances
Emotional and motivational functions Korsakoff: dorsomedial part thalamus (diencephalic amnesia) + frontal
- (medial area + role of amygdala)
Klüver-Bucy syndrome: (disinhibition)
Face perception (many areas) Bilateral anterior temporal lobe lesion
- Visual agnosia
Temporal lobe structures (hippocampus): explicit memory - Dietary habits: eat everything
- React to every stimulus
- RH: episodic - Hyperoral: put everything in mouth
- LH: semantic - Loss of fear
- Increase in erotic activity
Basal ganglia (striatum): implicit memory: skills, habits
Neocortex: implicit memory: priming
Cerebellum: conditioning, motor learning
Amygdala: emotional memory
Frontal + temporal lobe: STM
Left PFC: encoding
