EFFECT OF PHOTIC STIMULATION ON THE HUMAN MENSTRUAL CYCLE
Photochemistry and Photobiology, 1978Abstract— A theoretical rationale is presented to justify a study of the effect of light on the variability of the menstrual cycle. The experiment consisted of exposure to light all night for several consecutive nights of cycle days 14 through 17, day one being determined by the first day of menses.

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...

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.

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

Quantifying Changes in EEG Complexity Induced by Photic Stimulation
Methods of Information in Medicine, 2010Summary Objectives: This study aims to characterize EEG complexity, measured as the prediction error resulting from nonlinear prediction, in healthy humans during photic stimulation. Methods: EEGs were recorded from 15 subjects with eyes closed (EC) and eyes open (EO), during the baseline condition and during stroboscopic photic ...

EEG responses to photic stimulation in persons experienced at meditation
Electroencephalography and Clinical Neurophysiology, 1975The EEG responses to intermittent photic stimulation were examined in a group of subjects experienced in meditation, and compared with those of a control group. The meditators exhibited a significantly smaller decrement in alpha activity and alpha blocking over the course of the experiment than did the control group, and alpha induction occurred ...

Photic stimulation and visual physiology: Implications for behavioral studies
Behavioral Biology, 1973Behavioral studies using photic stimulation tend to ignore a multitude of complex relationships related to the interaction of light with the eye. Variations in retinal structure, photoreceptor sensitivity, light-dark adaptation, blink rate, and pupil size are uncontrolled.
