'''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)uring the electrical activity in their brains. Later he ceased the stimulus method and began measuring the natural rhythmic electrical cycles in the brain. The first natural rhythm 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 fuür 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 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.
