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 ...

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.

P517: Low intensity intermittent photic stimulation
Clinical Neurophysiology, 2014s 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 ...

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 ...

Photic Stimulation and the EEG in Macular Disease
Archives of Ophthalmology, 1964Berger in 1929 discovered what is now known as the a rhythm of the brain. This consists of oscillations of electrical potential at a frequency of 8½ to 12 per second and is best developed in the parieto-occipital region. This rhythm is best demonstrated with the eyes closed, and may be blocked by the subject's attention to vision with the eyes opened ...

Use of rhythmically varying patterns for photic stimulation
Electroencephalography and Clinical Neurophysiology, 1952Abstract 1. 1. A method of producing photic stimulation by means of a periodically altered pattern is presented to be used with EEG investigations. 2. 2. This method circumvents the more bothersome artifacts occasioned in the use of the standard strobe light. 3. 3. The “pattern driving effect” may be easily observed in the occipital leads

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 as a Training Aid in Psychotherapy
New England Journal of Medicine, 1957ONE definition of psychotherapy features the learning aspects of that process. For example, it has been said that in psychotherapy the patient partly unlearns some old patterns and learns some fres...
