Document Summary

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): a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task. Mri (magnetic resonance imaging): a technique that uses magnetic fields and radio waves to produce computer generated images of soft tissue. Mri scans show brain anatomy. fmri (functional mri): a technique for revealing blood flow and, therefore, brain activity by comparing successive mri scans. 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 skull; the brainstem is responsible for automatic survival functions. Medulla: the base of the brainstem; controls heartbeat and breathing.
