Alpha rhythm describes the pattern of alpha waves that occur when an individual is at rest but still awake. Alpha waves occur when a person has closed eyes but is alert and the alpha rhythm are the se [..]

A brain potential of 8–12 Hz that occurs during relaxed wakefulness. See Figure 14.10. Compare desynchronized EEG.

A uniform rhythm of brain waves in the normal eletroencephalogram, with an average frequency of about 8 to 13 cps.

EEG oscillations, prominent over the occipital cortex, with a frequency of 8-13 Hz in adults;  indicative of the awake state; present in most, but not all, normal individuals; most consistent and pred [..]

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 Occip [..]

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 t [..]

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)
