Brain wave band details.

Name	Frequency (Hz)	Location	Generated time
δ	0.5 < 4	Forehead in adults, back of brain in children	Occurs mostly in the brains of infants, but also occurs when adults are in deep sleep, coma, or anesthesia
θ	4–7	Brain regions unrelated to hand function	Occurs in young children and adolescents, but also in adults who are tired but conscious
α	8–15	The back of the brain, the resting state is concentrated in the center	Relaxed/contemplative state with eyes closed
β	16–31	The brain is symmetrically distributed on both sides, with a prominent forehead	Positive thinking, focus, vigilance, anxiety
γ	32–45	Somatosensory cortex	Short-term memory, hearing, and touch, multisensory processing
