Document Summary

Cerebral cortex (gray matter) thin layer, contain neuronal cell bodies: many folds (large sa), need more cells for cognitive functioning w/out expanding head.

Cerebral white matter: contains fibers connecting cell bodies to other cortical areas/rest of brain large amount of white matter cause gray needs to connect. *essential part of cerebral cortex and how it functions.

Primary somatomotor cortex: sends out demand to spinal (controls skeletal muscles) Integrates info to association cortex to make distinction. Primary sensory cortex: touch, sensation; aware of where and intensity of touch (info sent here) Primary visual cortex: bring in light intensity, colours. Auditory association: frequency and loudness since humans able to communicate cerebral uniquely developed. Wernicke area: speech comprehension (left side brain), right side responsible for tone.
