What is the difference between alpha and beta waves?
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.
What does it mean when your alpha waves are dominant?
When your brain’s alpha waves are dominating, you’re likely in a state of wakeful relaxation. Relaxation techniques like mindfulness and meditation may help increase your alpha waves. This, in turn, may help you feel calmer, less anxious, and, according to some studies, may even boost your creativity levels.

How to identify alpha waves?
Identifying Alpha Waves. There are five different types of brain waves. Brain waves are measured by a tool known as an electroencephalogram (EEG). The picture that the tool creates portrays this electrical activity in a way that looks like waves. An EEG looks at the frequency of these waves, or the cycles of activity per second.
What is the purpose of alpha waves?
Interest in the use of alpha waves grew after the development of biofeedback, a technique that involves using feedback from a tool that measures brain activity to learn how to consciously create alpha waves. Research has shown that alpha waves may have a number of positive benefits, which might include the following:
What are the different types of brain waves?
The five types of brain waves and their associated frequencies are: 1 Delta waves, which are between 0.5 and 4 hertz (Hz), occur during deep states of dreamless sleep. 2 Theta waves, which are between 4 and 8 Hz, occur during light sleep or deep relaxation. 3 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. 4 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. 5 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.
What is the frequency of the alpha rhythm?
Alpha rhythm (AR) is seen in relaxed adults with closed eyes; it has a frequency of 8–13 Hz over the occipital lobe and has bihemispheric asynchrony, where the non-dominant hemisphere has a greater wave amplitude. Focal CNS disease is accompanied by focally altered AR, which becomes diffuse in coma.
What is the EEG pattern that corresponds to the awake state?
AR is the EEG pattern that corresponds to the awake state; it is present in most, but not all, normal individuals, and is most consistent and predominant during relaxed wakefulness, particularly with reduction of visual input. AR has a range in each person: the low end is exhibited in drowsiness or sleep and the upper end with alertness. AR also varies with age: it is slower in children and older age groups relative to young and middle-aged adults.
