Brent is taking part in an experiment in a cognitive neuroscience lab on campus. Silently, he reads rapid sequences of words fla
shed on a computer screen. The electrical activity of his brain is simultaneously recorded through skull electrodes. The brain-scanning technique used in this study is ______.
The brain-scanning technique used in this study is electroencephalogram (EEG).
Explanation:
An electroencephalogram (EEG) is a test that evaluates electrical activity in our brains. As we know, our brain cells emit electrical impulses to "communicate" with each other. Through the use of electrodes - metal discs - attached to our scalps, those impulses can be detected and analyzed. An EEG can, therefore, find problems in the brain electrical activity.
