Alpha waves are produced by the brain when it is in a relaxed state with eyes closed, but not yet in deep sleep. Beta waves are produced when the brain is actively engaged in mental activities such as problem-solving or decision-making. Theta waves are produced in states of drowsiness, meditation, or light sleep. Delta waves are produced in deep sleep or states of unconsciousness. Gamma waves are associated with higher levels of cognitive processing and consciousness. Therefore, alpha waves are the best choice to describe the brain waves produced by normal adults while resting with their eyes closed.
