Document Summary

Phineas gage (1848: case study, construction worker. The damage to his frontal lobe caused a change in his personality. Very important for personality: damage to the frontal lobe alters personality, more spontaneous/impulsive. Damage: depression, over-expression of emotions, lack of planning, reduced motivation. Also, used when trying to control adhd. For example: when having a conversation with someone at least two areas of the brain are active: Primary somatosensory cortex: registers sensory neurons (touch, parietal lobe (anterior region) Primary motor cortex: registers the motor neurons (muscles, frontal lobe. Association cortex: registers complex functions, including higher-order sensory processing, integrating information from different senses, thinking, planning. Includes all the areas outside of the first two areas discussed (somatosensory a(cid:374)d (cid:373)otor cortex"s) Development of prosthetics that respond to activation of cells in motor cortex. A computer monitors the motor cortex and directs the prosthetic to make the intended movement.
