Theta waves are related to light sleep, relaxation, and meditation[10]. Alpha waves are linked to relaxed wakefulness, daydreaming, and creativity[10]. Beta waves are connected to active thinking, focus, and problem-solving[10]. Lastly, gamma waves are the fastest and are associated with high-level cognitive functioning, perception, and learning[10].
