Multiple response to photic stimulation in cats [PDF]

open access: yesAmerican 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 [PDF]

open access: yesBiomedical 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.

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

open access: yesComputers 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),

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.

Photic Stimulation

American Journal of EEG Technology, 1974
This contribution on photic stimulation is an attempt to stress its clinical value. The efficiency of photic stimulation is very poor if it is used to serve one purpose only, that is, testing a patient's photo convulsive threshold. Photic stimulation can be a much more powerful aid because driving responses make a positive contribution towards a better

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
