The Electroencephalographic Heritage Until 1960

 

Until the last few years the definition of “Electroencephalo­graph” has been described as “an electrical-brain-writer”. We came to think of an EEG as a multichannel device to economically record continuous “spontaneous” electrical brain potentials be­tween pairs of electrodes for hours at a time. With the advent of many possible ways of displaying electrical brain activity now in existence or in people’s minds, it appears that the definition may need to be broadened less it become obsolete.
