PSY 320 Lecture Notes - Lecture 14: Human Brain, Transcranial Magnetic Stimulation, Anhedonia
Document Summary
Just know main pieces of sensorimotor: reward centers. Many brain regions found to be rewarding with direct stimulation. Unconscious things driving behavior: history of reward center study. Inadvertely found if rats stimulated in certain place in chamber would develop a preference. Would press so much would(cid:374)"t eat, sleep etc. Once turn of the current, they just accept it and go on with lives. Unlike drug study where they will continue pressing even after stopping treatment: many parts of brain where can plan electrode and rats will work for electrical stimulation to brain. Possibly not even pleasurable, but work for it anyways: reward centers overlap with mesolimbic dopamine systems. As part of the hierarchy, reward can affect other behaviors co(cid:374)sider a(cid:374)hedo(cid:374)ia with schizophre(cid:374)ia, depressio(cid:374), parki(cid:374)so(cid:374)"s (co(cid:374)sider so(cid:373)e of the patients in awakenings. : human brain stimulation. Apply current directly to brain site (invasive) Electroconvulsive shock therapy- is effective in some cases for pulling someone out of a very deep depression.
