'''Alpha waves''' are [[Electromagnetic radiation|electromagnetic]] 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(contracted; show full)m he documented was what would become known as the alpha wave. Despite his brilliance, Berger was very thorough and meticulous in his data-gathering, and did not feel confident enough to publish his discoveries until at least five years after he had made them. In 1931, he published his first findings on alpha waves in the journal Archiv fur Psychiatrie. He was originally met with derision for his EEG technique and his subsequent alpha and brain wave discoveries. His technique and findings did not gain wide
-spread 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.

There are other uses of biofeedback training beyond therapy. Defense Department researchers are exploring biofeedback as a way of getting captured soldiers to create alpha waves, potentially foiling enemy lie detectors. Biofeedback training has also been receiving attention as a possible way of monitoring attention. It has been theorized that teaching machines could use biofeedback as a way of monitoring children
s's attention, with the appearance of alpha waves signaling a lapse of attention.<ref> Time. Behavior: Alpha Wave of the Future. Jul, 1971</ref>
