1. alpha rhythm

   Alpha waves, or the alpha rhythm, are neural oscillations in the frequency range of 8–12 Hz likely originating from the synchronous and coherent (in phase or constructive) electrical activity of thalamic pacemaker cells in humans. Historically, they are also called "Berger's waves" after Hans Berger, who first described them when he invented the EEG in 1924.Alpha waves are one type of brain waves detected by electrophysiological and closely related methods, such as by electroencephalography (EEG) or magnetoencephalography (MEG), and can be quantified using quantitative electroencephalography (qEEG). They can be predominantly recorded from the occipital lobes during wakeful relaxation with closed eyes and were the earliest brain rhythm recorded in humans. Alpha waves are reduced with open eyes and sleep, while they are enhanced during drowsiness. Historically, they were thought to represent the activity of the visual cortex in an idle state. More recent papers have argued that they inhibit areas of the cortex not in use, or alternatively that they play an active role in network coordination and communication. Occipital alpha waves during periods of eyes closed are the strongest EEG brain signals.An alpha-like variant called a mu wave can be found over the primary motor cortex.

1. alpha rhythm

   The alpha rhythm, also known as alpha waves, is a type of brain wave pattern that is typically associated with a relaxed, calm state of mind. It is usually measured using an electroencephalogram (EEG) and oscillates at a frequency between 8 and 12 hertz. It is most detectable when an individual is not focused on the outside world and is resting with closed eyes, but awake. Lower frequency alpha rhythms are often linked to feelings of relaxation, while higher frequency alpha rhythms are associated with alertness and mental coordination.

1. Alpha Rhythm

   One of four types of brain waves characterized by a relatively high voltage or amplitude and a frequency of 8-13 Hz. They constitute the majority of waves recorded by EEG registering the activity of the parietal and occipital lobes when the individual is awake, but relaxed with the eyes closed.
