Final answer:
An EEG, or electroencephalography, is used to measure Dwayne's brain waves during a sleep study to diagnose potential sleep disorders by examining electrical activity patterns.
Step-by-step explanation:
When Dwayne arrives at the sleep study to determine the cause of his difficulty sleeping, the doctors use a(n) EEG (electroencephalography) to measure his brain waves as he sleeps. The EEG involves placing an array of electrodes around a person's head to provide a measure of a brain's electrical activity. The sleep stages, characterized by different patterns of brain wave activity, including beta waves during wakefulness, and distinctive patterns during various stages of NREM and REM sleep, can be visualized using an EEG. This tool is essential for diagnosing sleep disorders and understanding how activity in the reticular formation is related to sleep and wakefulness.
The technique that the doctors would use to measure Dwayne's brain waves as he sleeps is an EEG (electroencephalography). EEG measures the overall electrical activity of the brain without providing information about the specific location of the activity. It involves placing an array of electrodes around a person's head to record the brain's electrical activity.
