Brainwave Frequencies: What Are They?

Brainwave Frequencies: What Are They?

Posted on: January 11th, 2022 by NeuroHealth Associates

Brain waves represent patterns of electrical activity produced by the brain. The brain is made up of billions of neurons that use electrical signals to transmit information. 

When groups of neurons fire together in a certain way to send signals to other groups of neurons, the resulting patterns are known as brain waves. These electrical patterns are associated with different types of activity in the brain as well as different states of consciousness.

Brain Wave Types

There are 5 major types of brain waves used in research and studies:

Alpha waves, which measure between 8 and 12 Hz, occur when people feel relaxed and when the brain is in an idle state without concentrating on anything.

Beta waves, which measure between 12 and 30 Hz, are the waves that occur during most conscious, waking states. It is a fast activity that signals attentiveness and alertness. 

Gamma waves, which measure between 25 and 100 Hz, are the fastest wavelength brain waves that are linked to activities such as learning, problem-solving, and information processing.

Delta waves, which are between 0.5 and 4 hertz (Hz), occur during deep states of dreamless sleep.

Theta waves, which are between 4 and 8 Hz, occur during light sleep or deep relaxation.

Brain Wave Functions

When the brain produces waves, it is because it is in a specific state. This is why people experience certain wave types when they engage in different types of behaviors and activities.

When the brain displays an EEG wave during testing, it often shows waves that correspond to the overall state of a person’s mind. For example; brains tend to ignore sensory activity and are in a relaxed state when alpha waves are high.

There is some evidence that suggests finding ways to boost certain types of brain waves may have a number of benefits. Some of the positive effects of boosting alpha waves include lowering stress, reducing anxiety, decreasing depression, and improving creative thinking.

What Clients Say About Us


Julie W.
Teachers made huge comments on his math skills and behavior. I also saw this at home with understanding of what I said to him registering more with him. I saw this in his eyes: recognition. Fewer outbursts of anger.

Anita M.
I am extremely happy with my son’s treatment outcomes and feel very fortunate to have encountered Dr. Bonesteel early in my child’s life. This treatment has dramatically changed his ability to focus and take initiative. I feel confident that my son’s life has been dramatically enhanced. I can’t express my appreciation fully in words.

Mary B.
Dr. Bonesteel has masterfully, compassionately, and extremely kindly helped me navigate through a history of childhood and marital abuse, a child with twenty years of struggle with life-threatening physical and emotional illness, extended family discord, and disharmony with my child with severe depression. I am blessed to have found Neurohealth Associates.
