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

a. True

b. False

The correct answer is B, false. Not all the time the brainwaves that pre-dominate the brain come from the conscious level because it may also come from the subconscious. The subconscious according to many psychologists is the seat of all emotions, where all desire and dreams come from, and they also form into brainwaves that are passed through the synapses of the brain.
