'''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 Berge(contracted; show full)were trained to withhold motor movement, they released SMR, or mu, waves, a wave similar to alpha waves. Using a reward system, he further trained these cats to enter this state easier. Later, he was approached by the United States Air Force to test the effects of a jet fuel that was known to cause seizures in humans. Sterman tested the effects of this fuel on the previously-trained cats, and discovered that they had a higher resistance to seizures than non-trained cats.

Alpha wave biofeedback has gained 
notorietyinterest for having some successes in humans for seizure suppression and for treatment of depression.<ref>Ulrich Kraft. Train Your Brain-Mental exercises with neurofeedback may ease symptoms of attention-deficit disorder, epilepsy and depression--and even boost cognition in healthy brains.

==Types of alpha waves==

Some researchers posit that there are at least three forms of alpha waves, which may all have different functions in the wake-sleep cycle.
