Document Summary
Psych 101 lecture 8 brain and behavior: cerebral cortex. Example: damage to the left hemisphere will affect the sensory/motor control on the right side of the body. Corpus callosum: bundle of axons that connect the two hemispheres; how the hemispheres communicate with each other: hemispheric lateralization: the two hemispheres have slightly different functions. Right hemisphere: primarily processes visual spatial information, is involved in holistic processing, and in recognizing and expressing emotion. Left hemisphere: processes language, sequential logical thinking, concerned with details. Lobes of the cerebral cortex: frontal lobe: involved in working memory, movement, speech and language production, judgment and planning, and personality. Phineas gage: a severe head injury due to a tamping iron; he experienced damage to the frontal lobe. Motor cortex: controls fine motor movements; each part of the motor cortex controls a different part of the body. Sensory cortex: contains neurons that are sensitive to touch in different parts of the body.
