An electroencephalogram, or EEG, can theoretically be recorded by:

A) a voltmeter.
B) a current meter.
C) an amp meter.
D) either a voltmeter or a current meter.

Electroencephalogram

A test that measures electrical activity in the brain using small electrodes attached to the scalp, used in the diagnosis of neurological conditions.

Voltmeter

Device that measures the strength of electrical voltage by recording the difference in electrical potential between two points.

Current Meter

An instrument used for measuring the velocity and direction of water flow in rivers, streams, and oceans.
