Slow-frequency waves that mainly occur in our sleep. Research has shown that stimulating the brain to produce more Delta waves can trigger a slowdown in brain activity that will aid relaxation and sleep. Sometimes, Delta waves also occur during drug-induced dreamlike states, marking a condition when the brain stays active while being disconnected from sensory feelings from the environment.

Often associated with feelings of calmness and with lower stress. Theta waves are also strong during meditation, prayer, and spiritual awareness, and are enhanced when you try to memorize new things or retrieve information from your memory.

Generated when the brain is stimulated and actively engaged in mental activities. Beta stimulation improves cognitive function, and physical performance, and is characteristic of a strongly engaged mind. We are in Beta when we are mentally active and attentive.

Occur when distant parts of the brain fire harmoniously, marking the simultaneous processing of complex information while performing demanding mental tasks. Stimulating the brain to produce more Gamma waves improves mental clarity and focus.
