Document Summary

lesions can cause irregular and jerky movements, tremors, impairment of balance and gait. shift attention between visual and auditory stimuli, rhythm: midbrain, inferior and superior colliculi relaying information between brain regions (cerebellum and forebrain, reticular formation helps keep us awake and more alert, sudden arousal to threat/attention-grabbing stimulus. Switching station for sensory information; involved in memory. Regulates basic biological functions (hunger, thirst, temperature, sexual arousal), involved in emotions. the assumption that the size of a portion of the brain corresponded to its relative power. Lateralization of function: the two cerebral hemispheres play different roles in some cognitive functions. Brain imaging techniques: cat computerized axial tomography, reflection of different densities of the body organs, pinpoint areas of brain damage and age of the injury. more precise localization of brain region activity: erp event-related potential, measures an area of the brain"s response to a specific event, electrodes are attached to the scalp.
