History

A timeline of the history of EEG is accustomed by Swartz.37 Richard Caton (1842–1926), a physician practicing in Liverpool, presented his allegation about electrical phenomena of the apparent bookish hemispheres of rabbits and monkeys in the British Medical Journal in 1875. In 1890, Polish physiologist Adolf Beck appear an analysis of ad-lib electrical action of the academician of rabbits and dogs that included adroit oscillations adapted by light.

In 1912, Russian physiologist, Vladimir Vladimirovich Pravdich-Neminsky appear the aboriginal beastly EEG and the evoked abeyant of the beastly (dog).38 In 1914, Napoleon Cybulski and Jelenska-Macieszyna photographed EEG-recordings of experimentally induced seizures.

German physiologist and analyst Hans Berger (1873–1941) recorded the aboriginal animal EEG in 1924.39 Expanding on plan ahead conducted on animals by Richard Caton and others, Berger aswell invented the electroencephalogram (giving the accessory its name), an apparatus declared "as one of the a lot of surprising, remarkable, and momentous developments in the history of analytic neurology".40 His discoveries were aboriginal accustomed by British scientists Edgar Douglas Adrian and B. H. C. Matthews in 1934 and developed by them.

In 1934, Fisher and Lowenback aboriginal approved epileptiform spikes. In 1935 Gibbs, Davis and Lennox declared interictal fasten after-effects and the 3 cycles/s arrangement of analytic absence seizures, which began the acreage of analytic electroencephalography. Subsequently, in 1936 Gibbs and Jasper appear the interictal fasten as the focal signature of epilepsy. The aforementioned year, the aboriginal EEG class opened at Massachusetts General Hospital.

Franklin Offner (1911–1999), assistant of biophysics at Northwestern University developed a ancestor of the EEG that congenital a piezoelectric inkwriter alleged a Crystograph (the accomplished accessory was about accustomed as the Offner Dynograph).

In 1947, The American EEG Society was founded and the aboriginal International EEG assembly was held. In 1953 Aserinsky and Kleitman call REM sleep.

In the 1950s, William Grey Walter developed an accessory to EEG alleged EEG topography, which accustomed for the mapping of electrical action beyond the apparent of the brain. This enjoyed a abrupt aeon of acceptance in the 1980s and seemed abnormally able for psychiatry. It was never accustomed by neurologists and charcoal primarily a analysis tool.
