Multiple response to photic stimulation in cats

American Journal of Physiology-Legacy Content, 1959
This study was carried out in order to compare the multiple cortical response to a photic stimulus and the secondary response to sciatic nerve stimulation. Late responses to flash and to sciatic nerve shock were recorded in acute cat preparations anesthetized with pentobarbital.

Detection of multiple sclerosis from photic stimulation EEG signals

Biomedical Signal Processing and Control, 2021
Background: Multiple Sclerosis (MS) is characterized as a chronic, autoimmune and inflammatory disease of the central nervous system. Early diagnosis of MS is of great importance for the treatment and course of the disease.

Spectral analysis of photic stimulation in migraine

Electroencephalography and Clinical Neurophysiology, 1982
In seeking an electrophysiologic discriminator of migraine, we applied computer technology to power spectral analysis of the EEG with photic stimulation. In 11 normal volunteers and 11 migraineurs (both classic and common) we were able to classify all migraineurs and misclassified only one normal based on the spectral analysis.

The evaluation of EEG response to photic stimulation in normal and diseased subjects

Computers in Biology and Medicine, 2009
In this paper, our aim is to determine two photic stimulation frequencies, which would represent normal and diseased subjects, separately. Following features were extracted for this aim: linear prediction coefficients (LPC) subband wavelet entropy (SWE),

Ictus Emeticus Induced by Photic Stimulation

Clinical Electroencephalography, 1988
It has been recently established that ictus emeticus originates from mesial temporal lobe structures. We herein report a patient with generalized epilepsy who exhibited ictus emeticus reflexly triggered by intermittent photic stimulation accompanied by generalized photoparoxysmal responses on the electroencephalogram. All seizures and EEG abnormalities

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 ...

Hemodynamic responses to photic stimulation in neonates

Pediatric Neurology, 2000
A three-channel near-infrared monitoring system was used to evaluate the regional hemodynamic responses to photic stimulation during spontaneous sleep in seven healthy neonates. Three pairs of parallel light guides, separated by 15 mm each, were placed over a 450-mm(2) occipital region of the head.
