We present a model for flicker phosphenes, the spontaneous appearance of geometric patterns in the visual field when a subject is exposed to diffuse flickering light. We suggest that the …

Entoptic Hallucination
Entoptic hallucination, geometric hallucinations, or phosphenes, are one of the most commonly reported visual effects of psychedelics. Phosphenes are a sensation of light caused by excitation of the retina by …
Electrophysiological correlates of flicker-induced form hallucinations
Form hallucinations can be reliably induced using temporally modulated light within a specific frequency range (15-30Hz). The neural substrates of such states have yet to be established with certainty. Brain …
Revelations by Flicker, Dream machines and Electroencephalographic signals in art
How did ordinary tools in the Neurophysiology department become a means for spiritual enlightenment? The combination of brainwave (EEG) monitoring by the early adopters with stroboscopes induced side-effects in many …
High Gamma Power Is Phase-Locked to Theta Oscillations in Human Neocortex
We observed robust coupling between the high- and low-frequency bands of ongoing electrical activity in the human brain. In particular, the phase of the low-frequency theta (4 to 8 hertz) …
Academic Performance Enhancement with Photic Stimulation and EDR Feedback
This study was designed to test the possibility that training with the Biolight, a combined audio/visual stimulation (AVS) and EDR feedback device, would result in positive changes in academic performance. …
Megabrain Report (1990)
In this issue we describe over 20 different light and sound machines. Most of these devices have appeared on the market in the last year or two. More and more …
The Infinite Mindfield
Anthony Peake discusses his book The Infinite Mindfield: The Quest to Find the Gateway to Higher Consciousness. The Infinite Mindfield uses as its starting point the widespread historical belief that …
Brainwave Frequency Listing
This is a listing of frequencies that various parties have claimed can affect the human mind or body in some way. The following sorts of frequencies are included : Brainwave …
Stanislav Grof on Non-Ordinary Consciousness
Paulson: What happened during that first experience? Groff: Well, my preceptor was very interested in electroenchepelography, which means exposing people to a stroboscopic light. So between the third and fourth …
