Question

An________ reveals the electrical activity of the brain by producing a record of brain waves. a _________ reveals activity in various parts of the brain based on patterns of blow flow, oxygen use, and glucose consumption.

Answer 1

An electroencephalogram (EEG) reveals the electrical activity of the brain by producing a record of brain waves. It is noninvasive and uses electrodes which are placed along the scalp. It records the electrical signals of the brain. This can help diagnose sleep disorders and epilepsy 

A PET Scan, which is short for positron-emission tomography, reveals activity in various pars of the brain based on patterns of blood flow, oxygen use, and glucose consumption. It is an imaging test that makes use of radioactive materials or substances called tracers. It helps to see how the brain functions and it can be used as a diagnostic test for disease or injury in the brain.
