Interference (wave propagation)
In physics, interference is the addition (superposition) of two or more waves that results in a new wave pattern. Interference usually refers to the interaction of waves that are correlated or coherent with each other, either because they come from t...
An Overview of Physical Shamanism
... timed rhythms and precisely shaped wave patterns to entrain both global and regional coherence of multi-stable neural oscillators. The techniques of physical shamanism are often used with a hallucinogen in order to entrance or hypnotize a s...

... to be close to the limit of resolution. 15. patterns of up to four phosphenes produced by four electrodes have been recognized. However, a variety of complex interactions have been reported. 16. Multiple phosphenes are co-planar, although pa...
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...
Altered States: The Origin of Art in Entoptic Phenomena

Psychedelic Information Theory

What Geometric Visual Hallucinations Tell Us about the Visual Cortex
