Varying states of awareness are best monitored using ____,which provides an overall measure of brain activity.
A)a CAT scan
B)magnetic resonance imaging
C)an electroencephalogram
D)positron emission tomography

Question

Quizplus · Accepted Answer

An electroencephalogram (EEG) is the best choice for monitoring varying states of awareness, as it measures the overall electrical activity of the brain in real-time. CAT scans and magnetic resonance imaging (MRI) are useful for examining the structure of the brain but do not provide information on brain activity. Positron emission tomography (PET) is a functional imaging technique that can measure brain activity, but it is less commonly used than EEG for monitoring changes in awareness.
