An polysomnograph displays:
A) action potentials of individual neurons.
B) a combination of EEG and eye-movement records.
C) the rate of glucose uptake in active regions of the brain.
D) the electrical resistance of the scalp.

Question

Quizplus · Accepted Answer

A polysomnograph typically displays a combination of electroencephalogram (EEG) and eye-movement records. These recordings can help identify different stages of sleep and evaluate sleep disorders. Option A is incorrect because action potentials of individual neurons are not typically measured in a polysomnograph. Option C is incorrect because the rate of glucose uptake in the brain is typically measured using positron emission tomography (PET) imaging, not a polysomnograph. Option D is incorrect because the electrical resistance of the scalp is not typically measured in a polysomnograph.
