Answer;

The above statement is true

The brain waves that predominate at any given time depend on a person’s state of consciousness.

Explanation;There are four brainwave states that range from the high amplitude, low frequency delta to the low amplitude, high frequency beta. These brainwave states range from deep dreamless sleep to high arousal. According to research, one brainwave state predominate at any given time, based on a person's activity level. When this happens the other tree brain states are present in the mix of brainwaves at all times.For example when someone is in an aroused state they exhibit a beta brainwave pattern.
