Document Summary

Module 5 tools of discovery and older brain structures. Electroencephalogram (eeg) an amplified recording of the waves of electrical activity that sweeps across the brain"s surface. These waves are measured by electrodes placed on the scalp: best for: to monitor the electrical activity in the brain that is triggered by hearing one"s own name, researchers would make use of this. Positron emission tomography (pet) a visual display of brain activity that detects where a radioactive form of glucose goes ( hot spots ) while the brain performs a task. Tracks gamma rays: best for: showing which brain areas are active when a person does mathematical calculations, looks at images of faces, or daydreams. Magnetic resonance imaging (mri) a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. Mri scans show brain anatomy: best for: evaluating soft tissue structures.
