Beta waves are the brain waves most closely associated with mental activity. They are high frequency and low amplitude waves that are present when the brain is active and engaged in cognitive tasks, such as problem-solving or decision-making. Alpha waves are associated with relaxation and meditation, theta waves with drowsiness and the early stages of sleep, and delta waves with deep sleep.
