Brent is taking part in an experiment in a cognitive neuroscience lab on campus. Silently, he reads rapid sequences of words flashed on a computer screen. Simultaneously, the electrical activity of his brain is recorded through skull electrodes. The brain scanning technique used in this study is:
A)computerized axial tomography (CAT).
B)electroencephalogram (EEG).
C)positron emission tomography (PET).
D)functional magnetic resonance imaging (fMRI).

Question

Quizplus · Accepted Answer

The brain scanning technique described in the scenario involves recording of electrical activity through skull electrodes while the participant performs a task. This technique is characteristic of an electroencephalogram (EEG). This is in contrast to techniques like CAT, PET, and fMRI, which rely on different physical properties of the brain (e.g., blood flow, energy absorption) to produce images or recordings.
