Delta waves are the slowest and highest amplitude brain waves that are associated with deep sleep, which occurs during stage 3 and 4 of the sleep cycle. This stage is usually reached within the first hour of falling asleep. Beta waves are smaller and faster and are associated with wakefulness, alpha waves are also smaller and slower than beta waves and are associated with relaxation or light sleep, and theta waves are slower and slightly larger than alpha waves and are associated with drowsiness and early stages of sleep. Tau waves are not a recognized type of brain wave.
