'''Alpha waves''' are [[neural oscillations]] in the frequency range of 8–12 [[Hertz|Hz]] arising from ''synchronous'' and ''coherent'' (''in phase''/''constructive'') electrical activity of [[Human thalamus|thalamic]] pacemaker cells in humans. They are also called [[Hans Berger|(contracted; show full)

Despite this, alpha wave intrusion has not been significantly linked to any major sleep disorder, including fibromyalgia, chronic fatigue syndrome (CNF), and major depression. However, it is common in chronic fatigued patients, and may amplify the effects of other sleep disorders.<ref>(1994). Alpha-delta sleep in patients with a chief complaint of chronic fatigue.

==Biofeedback 
Ttraining==

Given the alpha wave's connection with relaxed mental states, many people have latched onto the idea of utilizing this state through a technique called biofeedback training. This technique utilizes EEG to indicate to a subject or trainer when the subject is in an alpha wave state, which the subject is then instructed to remain in.
