Abstract
German psychiatrist Hans Berger (1873-1941) discovered and named the human electroencephalogram (EEG). He proved that alpha waves of the EEG were generated by cerebral cortical neurons and delineated the larger amplitude alpha rhythm with a mean frequency of 10-11. Hz, from the smaller amplitude 15-30. Hz beta waves. Berger showed that alpha waves disappeared with eye opening, and that the alpha rhythm slowed from normal frequencies in the presence of tumors and other pathology. Berger had hoped the EEG would be a mirror of the activities of the human mind.
