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 mechanical or electrical means. Pressure ...

The perception of patterns not resulting from viewing external objects but stimulated by cranial electrodes with pulse currents within the electroencephalographic frequency range ('phosphenes') has been investigated in earlier work. The experiments d...

... do, however, distinguish between entoptics and hallucinations. Entoptics are geometric patterns whose origins are in the nervous system itself, whereas hallucinations are iconic and culturally determined and may be experienced in all senses (aural...

... is unusual because is produces distinct audio hallucinations and little or no visual hallucinations, and predictably does not bond with targets associated with visual hallucination. By analyzing this affinity table it seems possible to predict th...
The psychotomimetic effects of short-term sensory deprivation
... often report perceptual disturbances such as hallucinations, especially over extended periods of time. However, there is little evidence concerning short-term sensory deprivation and whether its effects differ depending on the individual concern...
EEG coherence in post-LSD visual hallucinations
... certain individuals may result in chronic visual hallucinations, a DSM-IV syndrome known as hallucinogen persisting perception disorder (HPPD). We studied 38 HPPD subjects with a mean of 9.7 years of persistent visual hallucinations and 33 control s...

Notes on the Content of Hallucination
The content of psychedelic hallucinations has been described vividly in many places. See “Tripping” by Charles Hayes, or the Erowid Experience Valuts for hundreds of fascinating first person accounts. ...

What Geometric Visual Hallucinations Tell Us about the Visual Cortex
Many observers see geometric visual hallucinations after taking hallucinogens such as LSD, cannabis, mescaline or psilocybin; on viewing bright ickering lights; on waking up or falling asleep; in “near-death” experiences; and in many other synd...
A mathematical theory of visual hallucination patterns
Neuronal activity in a two-dimensional net is analyzed in the neighborhood of an instability. Bifurcation theory and group theory are used to demonstrate the existence of a variety of doublyperiodic patterns, hexagons, rolls, etc., as solutions to th...
