9/6/11 Peeking Inside the Brain Clinical studies Deep lesioning - insertion of a thin, insulated wire into the brain through which an electrical current is sent that destroys the brain cells at the tip of the wire. Electrical stimulation of the brain (ESB) – milder electrical current that causes neurons to react as if they had received a message. Human brain damage (e.g., Congresswoman Giffords) Menu

9/6/11 Peeking Inside the Brain Computed tomography (CT) - brain-imaging method using computer controlled X-rays of the brain. Positron emission tomography Menu Magnetic resonance imaging (MRI) - brain- imaging method using radio waves and magnetic fields of the body to produce detailed images of the brain. Functional MRI (fMRI) – computer makes a sort of “movie” of changes in the activity of the brain using images from different time periods.
