Photic Stimulation: Standardization of Screening Methods [PDF]

open access: bronzeEpilepsia, 1999
Summary:Purpose: Differences in methodology of intermittent photic stimulation within and between countries in Europe make collaborative research and interpretation of results difficult.Method: Experts in the field of photic stimulation from European countries have given an overview of methods used in routine photic stimulation.

Frequency of intermittent photic stimulation: Effect on photic afterdischarges, photic driving, and behavioral activity [PDF]

open access: bronzeBulletin of the Psychonomic Society, 1976
The effects of various frequencies of intermittent photic stimulation (1/7, 1/3.5, 1/1, 3/1, 6/1, 9/1, 15/1, 18/1, 24/1, and 60/1 sec) on photically evoked afterdischarges (PhADs), photic driving (PD), and behavioral activity (gridcrossings) were examined in rats.

Photoparoxysmal responses [PDF]

open access: yesArquivos de Neuro-Psiquiatria, 1990
Sixty-five outpatients with photoparoxysmal response (PPR) during routine EEG were studied. The PPR showed prevalence in women (75.4%). Seizures were found in 66.1% of cases.

Burst-Suppression EEG Reactivity to Photic Stimulation—A Translational Biomarker in Hypoxic–Ischemic Brain Injury [PDF]

open access: yesBiomolecules
The reactivity of an electroencephalogram (EEG) to external stimuli is impaired in comatose patients showing burst-suppression (BS) patterns following hypoxic–ischemic brain injury (HIBI).

Uniform decrease of alpha-global field power induced by intermittent photic stimulation of healthy subjects [PDF]

open access: goldBrazilian Journal of Medical and Biological Research, 2002
Nineteen-channel EEGs were recorded from the scalp surface of 30 healthy subjects (16 males and 14 females, mean age: 34 years, SD: 11.7 years) at rest and under trains of intermittent photic stimulation (IPS) at rates of 5, 10 and 20 Hz.

PHOTIC STIMULATION AND LEG MOVEMENTS IN THE CRAYFISH [PDF]

open access: hybridJournal of General Physiology, 1933
When Cambarus clarkii is exposed to a source of light so that both eyes are equally illuminated, leg movements of the two sides are equal in frequency and amplitude. On covering one eye and exposing the uncovered eye to light, leg movements on the side of the uncovered eye are more frequent and are of greater amplitude than on the side ...
