As a person becomes drowsy and enters the first stage of sleep, their brain waves will shift from the higher frequency alpha waves to the lower frequency theta waves. Therefore, you would expect to observe alpha waves first, followed by theta waves. Delta waves typically appear in deeper stages of sleep.
