'''Alpha waves''' are [[Electromagnetic radiation|electromagnetic]]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|Berger]]'s wave in memory of the founder of EEG.
