Intermittent photic stimulation affects motor cortex excitability in photosensitive idiopathic generalized epilepsy

Epilepsy Research, 2013
To assess the effect of intermittent photic stimulation (IPS) at a common activating frequency, i.e. 20Hz, on motor cortex excitability by means of transcranial magnetic stimulation (TMS) in photosensitive patients with idiopathic generalized epilepsy (IGE).We studied 15 photosensitive IGE patients showing a photoparoxysmal response (PPR) to IPS at ...

P517: Low intensity intermittent photic stimulation

Clinical Neurophysiology, 2014
s of Poster Presentations / Clinical Neurophysiology 125, Supplement 1 (2014) S1–S339 S189 motor threshold, respectively. The ISI of TS was 5 s. Five types of pulse trains were delivered in a pseudo-random order. The ISIs between 3 ISs and between the last IS and TS were (a) 250 ms and 500ms, (b) 500 ms and 500 ms, (c) 1000 ms and 500 ms, (d) 500 ms ...

Interhemispheric differences in photosensitive epilepsy. II. intermittent photic stimulation

Electroencephalography and Clinical Neurophysiology, 1981
Of a consecutive series of 138 photosensitive epileptic patients 57 showed a unilateral preponderance of asymmetrical discharges on IPS, significant in each individual at the 5% level. There was no association between asymmetry of IPS-induced discharges and clinical evidence of cerebral pathology (partial or secondary generalized epilepsy, neurological

Intermittent photic stimulation. Clinical usefulness of non-convulsive responses

Electroencephalography and Clinical Neurophysiology, 1978
The clinical usefulness of non-convulsive responses induced by intermittent photic stimulation (IPS) was studied in 46 patients whose evaluation included both electroencephalography (EEG) and computerized cranial tomography (CT scan). Three patterns of photic responses were identified and related to background EEG activity and type of lesion seen on CT

Spatial Structure of Brain Electric Fields during Intermittent Photic Stimulation

Neuropsychobiology, 2001
EEG changes in 27 young healthy male right-handed volunteers on intermittent photic stimulation (IPS) were estimated using global field power (GFP), EEG microstate modeling and analysis (EMMA), and low-resolution electromagnetic brain tomography (LORETA). The GFP significantly increased at flashing frequency and high harmonics.

Occipitotemporal seizures with ictus emeticus induced by intermittent photic stimulation

Neurology, 1994
We recorded occipitotemporal seizures induced by intermittent photic stimulation in three children with brain injuries, aged 10 to 13 years. All had a history of seizures and showed occipital spikes on EEG, but were seizure free and were not being treated at the time of investigation.

Nystagmus evoked by intermittent photic stimulation of the rabbit's eye

Experientia, 1965
Monokulare Reizung des Kaninchens durch Lichtblitze ruft einen Nystagmus hervor, dessen Richtung identisch ist mit der Richtung der Augenbewegungen, die durch elektrische Stimulierung des ipsilateralen Nervus opticus verursacht werden. Die anhaltende Beleuchtung des kontralateralen Auges hemmt die Nystagmusreaktion.

The treatment of congenital idiopathic nystagmus by intermittent photic stimulation

Ophthalmic and Physiological Optics, 1983
Abstract An analysis is presented of the results obtained by treating 54 patients with congenital nystagmus using intermittent photic stimulation. The major beneficial effect has been to improve the visual acuity, though the nystagmus itself is sometimes reduced in amplitude or even eliminated; an unexpected bonus, in certain cases, is the improvement ...

Maturational changes of 5 Hz SSVEPs elicited by intermittent photic stimulation

International Journal of Psychophysiology, 2010
We investigated the development of the magnitude and phase alignment of steady-state visual evoked potentials induced by 5 Hz intermittent photic stimulation in 46 children (3 to 16 years) and 8 adults, as a function of age. We found that, over the occipital region, magnitude values were the highest in 8-11-year old children, but decreased with age ...
