Question

When awake and alert, the brain is generating ________ waves that are detectable with an electroencephalogram.

A) epsilon
B) gamma
C) alpha
D) delta
E) beta"

Answer 1

The brain generates alpha waves when awake and alert that are detectable with an EEG. Alpha waves have a frequency of 8-12 Hz and low amplitude. Beta waves dominate brain wave activity during wakefulness.

Step-by-step explanation:

The brain generates alpha waves when awake and alert that are detectable with an electroencephalogram (EEG).

Alpha waves are characterized by a frequency of 8-12 Hz and relatively low amplitude. They resemble the brain wave patterns of someone who is relaxed but awake. The brain wave activity changes as we fall asleep, and different patterns of brain waves occur during different stages of sleep.

During wakefulness, the brain wave activity is dominated by beta waves, which have the highest frequency (13–30 Hz) and lowest amplitude, showing more variability compared to brain wave patterns during sleep.
