SUMMARY
The ABOVE printout is of EEG as it currently obtained by electrodes placed on the scalp.
Hans Berger began EEG studies in 1923 and published results in 1929. One century later, in 2023 electrophysiology is a different world. For not only electrophysiology; but, digital technology is the era we live in.
COMMENTS.
There is no refuting that Sigmund Freud, “The Interpretation of Dreams”, 1899 was a historic publication by the psychiatrist, that created research interest.
Nathaniel Kleitman, ”Sleep and Wakefulness”, 1963 give us a new term “rapid eye movements” (REM). Lee DeForest was the one who invented the “amplifier” that allowed Hans Berger to measure small electric currents.
The image ABOVE is of the blood vessels of the head. Hans Berger (1929) proved that blood chemical energy in the head was converted into electrical brain waves, now referred to as EEG.
