Question

Quizplus · Accepted Answer

An electroencephalogram (EEG) is a non-invasive test that measures and records the electrical activity of the brain using small, flat metal discs (electrodes) attached to the scalp. It is specific to measuring the electrical activity of neurons in the brain and is therefore the best choice for measuring the tiny bursts of electricity emitted by firing synapses. The other options, such as electrocardiogram and electromyogram, measure electrical activity related to the heart and muscles, respectively.
