Brain waves in the encephalogram which have a frequency of 8 to 13 per second. They are typical of the normal person awake and in a quiet resting state, and occur principally in the occipital region. ... (12 Dec 1998) ... 
uniform rhythm of waves in the normal electroencephalogram; see alpha waves.
Type: Term Definitions: 1. a wave pattern in the encephalogram in the frequency band of 8-13 Hz; 2. the posterior dominant 8-13 Hz rhythm in the awake, relaxed person with closed eyes, that attenuates with eye opening. Synonyms: alpha wave, Berger rhythm
