How Flickering Light Induces Hallucinations

Not directly related to psychedelics, HPPD or schizophrenia but the article speaks about how the visual cortex can be influenced and affected.

 

Key Facts:

• Flickering lights create standing waves in the visual cortex, altering perception.
• High-frequency light leads to finer, more detailed hallucinations.
• Study provides the first direct evidence linking brain waves to hallucinations.

Good find... this may explain the "geometric pattern" visuals in some people with HPPD and other phenomena.  Since our perceptual filter is so broken in the visual cortex in the first place, we experience this phenomena - in fact a reaction found in the overall population at large - in a magnified form.  I dig it.
