Alpha waves, or the alpha rhythm, are neural oscillations in the frequency range of 8–12 Hz [1] likely originating from the synchronous and coherent (in phase or constructive) electrical activity of thalamic pacemaker cells in humans.
Alpha Waves. This frequency range bridges the gap between our conscious thinking and subconscious mind. In other words, alpha is the frequency range between beta and theta. It helps us calm down when necessary and promotes feelings of deep relaxation.
Alpha waves are a medium-frequency pattern of brain activity associated with restful and meditative states. These waves measure between 8 and 12 Hz, indicating the brain is active but relaxed. While researchers are still learning more, there is some evidence that alpha waves play an important role in well-being.
Brain waves are measured by frequency, which is cycles per second, or hertz (Hz), and they range from very slow to very fast. Alpha waves fit in the middle of the spectrum, between theta...
Alpha brain waves are considered slower brain wave activity with oscillations that range from 8 Hz to 12 Hz (cycles per second). The alpha wave is typically produced by the right hemisphere of the brain, but often is synchronized across both right and left hemispheres on an E.E.G.
An alpha wave is defined as a type of brain wave that falls within the frequency range of 8-13 Hz. These waves are typically observed in relaxed states with minimal mental activity, especially during wakefulness.
In the deeper layers, slower oscillations called alpha and beta waves predominate. The universality of these patterns suggests that these oscillations are likely playing an important role across the brain, the researchers say.
