Doreen Pang Mrs. Trainor AP Psychology 12 October 2016 Module 5-1: The Brain The Tools of Discovery Lesion (Tissue destruction) destroy EEG the electrodes on head Usually used for sleeping waves PET looks at radioactive glucose Looks at molecular cellular structure allows for us to detect disease early MRI magnetic fields and radio waves to look at soft tissue Brainstem Oldest structure Responsible for older structures Base is Medulla controls heartbeat and breathing damage=death Pons Above the medulla helps coordinate movement Reticular Formation (Reticular Activating System) Runs all the way down the brainstem think nylons controlling arousal damage=coma Thalamus on top of brainstem directs messages to the sensory areas (except smell) Cerebellum ?little brain?
