title: Wavelength dependency of photoparoxysmal responses in photosensitive nonepileptic subjects.
abstract: Using specially made optical filters, we analyzed the wavelength dependency of photoparoxysmal responses (PPRs) in five photosensitive nonepileptic subjects. The wavelength spectrum around 700 nm (680-700 nm) was estimated as the only visible spectrum essential for eliciting PPRs in two normal trichromat nonepileptic subjects, although the effect of some wavelength spectra (360-400 nm and 520-580 nm) was uncertain. The wavelength dependency of PPRs in two photosensitive nonepileptic subjects was the same as that found in some patients with photosensitive idiopathic generalized epilepsy.
