Document Summary
Cerebellum: extends from the rear of brainstem looks like miniature brain limbic system, shaped like a doughnut involved in emotion, memory, and motivation limbic system includes. Amygdala influences aggression and fear: size of 2 lima beans, stimulate amygdala. Mellow animals either prepare to attack or cower in fear: memories about things to approach and avoid, animals without amygdala are difficult to condition. Speaking, muscle movement, planning, judgment: parietal lobe. At the top rear of brain receives sensory input for touch and body position: occipital lobe. Back of head involved in vision temporal lobes. Sides of head, just above ears involved in hearing. Sensory projection areas that receive input from the somatic sensory organs. Motor projection areas send output to the muscles. All other cortical areas (75% of cortex) Visual/auditory cortex: projection areas: where cortex receives input from periphery, visual cortex occipital lobes, auditory cortex temporal lobes. Brain function lateralization: asymmetry in the function of the cortical hemispheres left brain.
