You are watching sleep researchers monitor the sleep of a normal adult. The participant is hooked up to an EEG. What brain waves would you observe as the person becomes drowsy and then
Enters the first stage of sleep?
A) alpha eventually replaced by delta
B) delta eventually replaced by theta
C) alpha eventually replaced by irregular
D) delta eventually replaced by beta
Alpha Waves
The brain wave pattern associated with deep relaxation.
Delta Waves
Slow brain waves that are present in deep sleep and in brain activities associated with unconsciousness.
EEG
Electroencephalography, a noninvasive method to record electrical activity of the brain used in the diagnosis of neurological disorders, sleep disorders, and for research in neuroscience.

Final Answer :
C
Explanation :
As a person becomes drowsy and enters the first stage of sleep, alpha waves, which are associated with relaxation and a wakeful state, are eventually replaced by more irregular, lower frequency theta waves. This transition marks the shift from wakefulness to the initial stage of sleep.
