Document Summary
Cerebral cortex: the interconnected neurons that cover the cerebral hemispheres body"s ultimate control and information-processing centre. Wrinkly because without them it would require 3x the area it takes up. Thin surface area that contains a shit ton of neurons. Each hemisphere has 4 lobes and are separated by fissures/folds. Frontal lobes: just behind forehead; involved in speaking and muscle movements, as well as making plans and judgements (pre-frontal) Motor cortex: in the rear of the frontal lobe that controls voluntary movements. Parietal lobes: lies at the top of the head and includes areas involved in receiving sensory inputs for touch and body position. Occipital lobes: lies at the back of the head and includes areas involved in receiving information from the visual elds. Temporal lobes: lies above each of the ears; includes the auditory areas that each receive information from the opposite ear. Somatosensory cortex: the input; the left hemisphere receives input from the body"s right side.
