May 9, 2023 · Brain waves are electrical impulses that flow through the brain, creating patterns of activity. They are measured in cycles per second, or hertz (Hz). There are four main types of brain waves: alpha, beta, delta, and theta. Each type of brain wave is associated with a different state of consciousness.

Gamma waves are the highest frequency brain wave. They are measured in the range of 25-100 Hertz, although they are mostly measured at 40 Hertz. As mentioned above, higher frequency waves are correlated with elevated neural activity. High neural activity occurs during formation of ideas, language and memory processing, and various types of learning...
Beta waves are the second highest frequency brain wave. They are measured in the range of 12-38 Hertz. These waves are indicative of normal activity in the brain when we are conscious and alert. Most of our lives are spent in this type of brain wave, which is also why abnormalities in beta waves can be linked to various mental illnesses. Individual...
Alpha waves occur in the conscious state just like gamma and beta waves. However, alpha waves are measured at 8-12 Hertz, and are seen when not much information processing is required. Most often, these waves are present just before an individual drifts into sleep, or just as they are waking up in the morning. Interestingly, the moment that an indi...
Theta waves are a very low-frequency brain wave. Measured at 3-8 Hertz, theta waves are most often seen during light sleep and REM sleep. Theta waves can also be present during extreme relaxation, or in a suggestible hypnotic state. Theta waves are also extremely important in memory consolidation. The transition from engaging with our surrounding e...
Delta waves are the lowest frequency wave and occur in very deep, dreamless sleep. These waves are measured at 0.2-3 Hertz. When experiencing delta waves, you are completely unconscious. When dominant, these waves outline a state in which the body is able to recover from activities of the previous day. Essentially, the body is taking advantage of t...

Brainwaves are electrical readings that reflect brain activity. These electrical impulses can vary in speed and are measured in cycles per second, or hertz (Hz). You can detect a person’s mental state and measure the electrical activity in specific brain areas related to a particular brain function while looking at the brainwave activity.
Dec 22, 2023 · Brain state work can be couched in terms such as alpha, delta and so forth. However, this is actually referring to brain waves which specifically come from measuring brain activity using EEG.

Sep 12, 2023 · Alpha brain waves represent one pattern of electrical activity produced by the brain. The brain can produce slower or faster partners of activity, and alpha waves lie somewhere in the middle of this range.
Your brain creates simple electricity through an electrochemical process measured in the form of brainwaves. Brainwaves occur at different frequencies depending on what the brain is doing. By measuring these frequencies, using qEEG, it is possible to see where the brain is functioning less optimally.
