Contribution of intermittent photic stimulation to routine EEG

Neurophysiologie Clinique, 2021
Intermittent photic stimulation (IPS) is an activation procedure performed during electroencephalography (EEG) to detect photosensitive patients. This procedure is recommended in routine EEGs but the benefit of IPS in the general population is not clearly ascertained.We retrospectively analyzed 7683 EEGs of patients referred for a routine EEG to the ...

Alteration of motor cortex excitability in response to intermittent photic stimulation

Clinical Neurophysiology, 2000
To measure the duration of cortical silent period (C-SP) in response to different frequencies of intermittent photic stimulation (IPS).Ten normal volunteers without a history of seizures were studied. First, using a magnetic stimulator we determined the resting motor threshold (RMT).

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 ...

Techniques of Intermittent Photic Stimulation and Paroxysmal Responses

The American Journal of EEG Technology, 1989
Visual stimuli of flickering geometric pattern and red flicker are generally very potent stimuli in triggering paroxysmal responses irrespective of using light stimulation with very low intensity, ...

Facilitatory Effects of Intermittent Photic Stimulation on Visual Cortical Kindling

Epilepsia, 1982
Summary: There are few reports on kindling preparation by daily electrical stimulation to the primary visual cortex. In our previous studies on cats, it was demonstrated that repeated stimulation to the primary visual cortex brought a similar progress in seizure development as in amygdaloid kindling, although it took more trials.

Enhancement of Rolandic Mu Rhythm by Intermittent Photic Stimulation

The American Journal of EEG Technology, 1993
ABSTRACT.We present an unusual phenomenon seen while looking for epileptiform disturbance on a routine EEG examination of a young woman. During intermittent photic stimulation (IPS), irrespective of flash frequency, a prominent 10 Hz bicentral mu rhythm was consistently evoked.

The effect of background illumination on sensitivity to intermittent photic stimulation

Electroencephalography and Clinical Neurophysiology, 1980
Sensitivity to intermittent photic stimulation (IPS) was tested in 23 photosensitive epileptic subjects under conditions of normal and reduced ambient lighting. Darkening the room to 20 lux did not increase either the incidence of photosensitivity or the effective range of flash frequencies.
