Document Summary
Week two || lecture two || chapter two. One of the basic principles of brain organization is localization of function specific functions are served by specific areas of the brain. Most of the cognitive functions are served by the cerebral cortex , which is a layer of tissue about 3 mm thick that covers the brain. The cortex is the wrinkled covering you see when you look at an intact brain. Early evidence for localization of function came from neuropsychology the study of the behavior of people with brain damage. Frontal : receives all senses and coordination, control processes, broca"s area [left frontal lobe]: speech. *parietal: somatosensory cortex[perceptions of touch, pressure, pain]; not specific to one type processes important for attention. Temporal: computer visual, hearing(auditory cortex; upper), wernicke"s area: fluency of speech/ grammar; [damage lower right side] leads to prosopagnosia- inability to recognize faces.
