Brain Waves and EEG ⚫ Normal brain function involves continuous electrical activity ⚫ Brain Wave – The undulations in the recorded electrical potentials – Change with age, sensory stimuli, brain disease, and the psychoses ⚫ An electroencephalogram (EEG) – The entire record of the brain wave – be used to diagnose and localize brain lesions, tumors, infarcts, infections, abscesses, and epileptic lesions – A flat EEG (no electrical activity) is clinical evidence of death
