Beta (Beta2, 15-22Hz) is high engagement or actively figuring something out. Beta is a ‘fast’ activity, present when we are alert, attentive, engaged in problem solving, judgment, decision making, or focused mental activity.īeta brainwaves are further divided into three bands Lo-Beta (Beta1, 12-15Hz) can be thought of as a 'fast idle', or musing. Beta waves (12 to 38 Hz)īeta brainwaves dominate our normal waking state of consciousness when attention is directed towards cognitive tasks and the outside world. Alpha waves aid overall mental coordination, calmness, alertness, mind/body integration and learning. Alpha is the resting state for the brain.
Alpha is ‘the power of now’, being here, in the present. Alpha waves (8 to 12 Hz)Īlpha brainwaves are dominant during quietly flowing thoughts, and in some meditative states. It’s where we hold our ‘stuff’, our fears, troubled history, and nightmares. In theta we are in a dream vivid imagery, intuition and information beyond our normal conscious awareness. It is that twilight state which we normally only experience fleetingly as we wake or drift off to sleep. In theta, our senses are withdrawn from the external world and focused on signals originating from within. Theta is our gateway to learning, memory, and intuition. Theta brainwaves occur most often in sleep but are also dominant in deep meditation. Healing and regeneration are stimulated in this state, and that is why deep restorative sleep is so essential to the healing process. Delta waves suspend external awareness and are the source of empathy. They are generated in deepest meditation and dreamless sleep. Delta waves (.5 to 3 Hz)ĭelta brainwaves are slow, loud brainwaves (low frequency and deeply penetrating, like a drum beat).
Their slow nature make them difficult to detect and accurately measure, so few studies have been done. They appear to take a major role in brain timing and network function. Infra-Low brainwaves (also known as Slow Cortical Potentials), are thought to be the basic cortical rythms that underlie our higher brain functions. Very little is known about infra-low brainwaves.
