Your brain produces beta waves when you’re in an active, busy state. While alpha waves are present in both the waking and sleeping states, they are more prominent in the latter. You may also feel a sense of calm and clarity. When you’re calm, your breathing and heart rate slow down, and blood flow decreases to your muscles. Alpha waves are 8-12 Hz and are associated with a feeling of wakeful relaxation. In a relaxed state, your brain produces alpha waves. In general, brainwaves are divided into four basic types: delta, theta, alpha, beta, and gamma. Research has also shown that gamma waves can be increased through meditation and other mindfulness practices.Īnalyzing brainwaves with neurofeedback devices shows clear distinctions between the various ranges of frequencies and amplitudes, meaning that brainwaves can be divided into distinct types. Generally, gamma waves are thought to help the brain process information more quickly and effectively. This electrical activity can be measured using neurofeedback (typically through an electroencephalograph (EEG)) or mapped out more in-depth by a qEEG brain mapping. Gamma brainwave abnormalities have also been linked to several learning and memory problems.īrainwaves are electrical activity produced by neurons firing in the brain. They are associated with peak concentration, alertness, creativity, and positive mood states. Gamma brainwaves are generally accepted as ranging from 30 Hz to 80 Hz. Gamma brainwaves are the fastest and most energetic of all brainwave frequencies, however the accepted range for each of the different types of brainwaves varies.
