Dr.Baker is studying the activity in the brain of a participant when they are in REM sleep and comparing that to the activity when they're fully alert.Given this goal,what is the best technique for Dr.Baker to use?
A) diffusion tensor imaging
B) magnetic resonance imaging
C) electroencephalogram
D) positron emission tomography

Question

Quizplus · Accepted Answer

Electroencephalogram (EEG) is the most appropriate technique for studying brain activity during sleep and comparing it to alertness as it measures the electrical activity in the brain. EEG is non-invasive and has a high temporal resolution, which allows for measuring millisecond-level changes in brain activity. In contrast, diffusion tensor imaging and magnetic resonance imaging mainly capture structural images of the brain, while positron emission tomography is more suitable for studying metabolic and neurotransmitter changes in the brain, but it involves exposing the participant to radiation.
