'''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)iscoveries. His technique and findings did not gain widespread acceptance in the psychological community until 1937, when he gained the approval of the famous physiologist [[Edgar Douglas Adrian, 1st Baron Adrian|Lord Adrian]], who took a particular interest in alpha waves.<ref>Karbowski K. Hans Berger (1873-194). Journal of Neurology. 249(8):1310-1311</ref>

Alpha waves again gained recognition in the early 1960’s and 1970’s with the creation of a [[biofeedback]] theory relating to brain waves
  (see below). Such biofeedback, referred to as a kind of [[neurofeedback]], relating to alpha waves is the conscious elicitation of alpha brainwaves by a subject. Two different researchers in the United States explored this concept through unrelated experiments. Dr. Joe Kamiya, of the University of Chicago, discovered that some individuals had the conscious ability to recognize when they were creating alpha waves, and could increase their alpha activity. These individuals were motivated through a reward syst(contracted; show full)[[de:Elektroenzephalografie#Alpha-Wellen]]
