'Time-scribe': a universal time writer for any EEG/polygraph chart recorder.

Abstract

An ubiquitous digital clock 'time-scribe' with a unique pen-galvanometer writer section has been described which should greatly improve the correlation of a long term EEG with any other time related event or medium. The output of the clock generates on any pen-galvanometer based chart recorder numerical and some alpha characters which are easily and immediately readable. Because of its convenience, simplicity and basic practical application it should also stimulate discussion for the unification of time write-out standards and methods.
