PSYC 111 Lecture Notes - Lecture 11: Brain Damage, Neurogenesis, Muscle Tone
Document Summary
Located in the rear of the frontal lobe. Located in the front of the parietal lobe: processes sensory information from the body. Connects the two hemispheres of the brain.

Experiments: split-brain subjects could not name objects shown to the right hemisphere, but if asked to select these objects with their left hand, they succeeded. Located in the (left) temporal lobe: is involved in language comprehension. Located in the (left) frontal lobe: directs the muscle movements in speech production. Brain damage studies: early research focused on persons with partially- damaged brains: phineas gage, lesio(cid:374) affe(cid:272)ti(cid:374)g we(cid:396)(cid:374)i(cid:272)ke"s a(cid:396)ea. Lesion method: later research involved intentional destruction of small parts of animal brains. Electroencephalogram measures the electrical activity of the brain. Magnetic resonance imaging shows structure of the brain. Positron emission tomography measures the biochemical activity on the brain.
