Abstract
Few techniques are available which have as their aim the quantitative determination of a physiological function of the human brain. Of these the photomyoclonic threshold has received most attention and numerous reports have appeared concerning findings in epilepsy, schizophrenia, other psychiatric conditions and normal controls (2, 4, 5, 9, 10, 11, 14). The precise neuro-physiological meaning of the “threshold” is unknown but since the first publications of Gastaut (5) it has been widely assumed that the measure is one of diencephalic function and that a change in the latter can be detected by the resulting threshold change.Keywords
