Chapter 5 Electroencephalogram (EEG) - an amplified recording of the waves of electrical activity that sweep across the brain’s surface. These waves are measured by electrodes placed on the scalp PET (positron emission tomography) scan - a visual display of brain activity that detects where a radioactive form of glucose goes when the brain performs a given task MRI (magnetic resonance imaging) - a technique that uses magnetic fields and radio waves to produce computer-generated images that distinguish among different types of soft tissue; allows us to see structures within the brain fMRI (functional magnetic resonance imaging)- a technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans. MRI scans show brain anatomy, fMRI scans show brain function. Brainstem - the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skill; the brainstem is responsible for automatic survival functions Medulla- the base of the brainstem; controls heartbeat and breathing
