Hemodynamic responses to photic stimulation in neonates
Pediatric Neurology, 2000A 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.

Photic-stimulation in three species of baboons
Life Sciences, 1967Abstract A high percentage of baboons of the species Papio papio have presented evidence of photomyoclonic epilepsy (2, 3 and 4). Four of the first group of 10 from Senegal (tested in the laboratories of Dr. R. Naquet, C.N.R.S.-I.N.P. 3, Marseille, France) presented characteristic clinical and electroencephalographic signs of the syndrome (2). Later,

Multiple response to photic stimulation in cats
American Journal of Physiology-Legacy Content, 1959This 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.

EXPERIENCE WITH PHOTIC STIMULATION IN PSYCHIATRIC RESEARCH
American Journal of Psychiatry, 1957Intermittent photic stimulation has been of value in psychiatric research in a number of areas which include: (1) the development of screening techniques based upon the EEG driving response and subjective responses to photic stimulation; (2) correlated studies of photic stimulation with psychological tests; (3) studies relating driving response to ...

The application of electro-luminescence to photic stimulation
Electroencephalography and Clinical Neurophysiology, 1966Abstract A new method of photic stimulation is described which uses two electro-luminescent panels mounted in a pair of goggles. When suitably excited by AC, the panels become uniformly illuminated over the whole surface. Flicker is produced by modulating the exciting AC, and a circuit is given for producing square wave modulation of the panel ...

Photic Stimulation, Imagery, and Alpha Rhythm
Journal of Mental Science, 1956Photic stimulation, the exposure of the human eye to repetitive flashes of light, has been employed in recent years in three ways; as a diagnostic, as a therapeutic, and as a research method. In each case, its use has opened new frontiers of inquiry into the borderlands of neurology and psychology.This paper presents certain observations which stem ...

The role of photic stimulation in the induction of hypnotic trance
International Journal of Clinical and Experimental Hypnosis, 1964Abstract The relative effectiveness of the ordinary verbal method of trance induction is compared with 2 forms of induction utilizing mechanical photic stimulation, and with methods combining the personal and mechanical features. The criterion of trance adopted was the compulsive carrying out of a difficult suggestion.

Responses to photic stimulation in patients with occipital spikes
Electroencephalography and Clinical Neurophysiology, 1998To determine the effect of intermittent photic stimulation (IPS) and frequency of asymmetric driving responses in patients with occipital spikes.The amplitude of the driving response at 4 flash frequencies was measured from a referential montage in 60 patients with occipital spikes and in 60 normal EEG records from age-matched patients.
