Entheogens delivered by strobe ! what do phosphenes look like?

Entheogens delivered by strobe ! what do phosphenes look like?

these are actually all animations you can see here: www.brainmachine.co.uk/o…/pandorastar/visualisations/

These entoptic moving shapes are just some of the psychedelic patterns we try to describe after a Pandorastar lucid strobe light session.. I have researched the history in Ophthalmics and Physics from Jan Purkinje and Helmholtz from the 1820s who called them ‘Shadow Patterns’ and ‘Form…

The Entoptical Art

Today I learned what causes those colorful patterns that show up after you press on or rub your closed eyes enough in a dark room. "Entoptic" phenomena are visual hallucinations which originate within the eyeball itself. The actual explanation is pretty technical, so I will crib extensively from the linked post (go give them a click):

When you apply pressure to the eye ball, what you're doing is pressing on the retina and the retina is the extremely complicated, cell-rich, very highly metabolically active structure that turns light waves into brain waves, to put it simply.

When you apply pressure to the retina, two things happen. One, you deform the retina a little bit and this makes the photo receptors, which are the specialised cells that pick up photons of light and change their pattern of firing activity in response to them which is how we see, it makes those cells change their activity. The other thing that pressing on the retina would do is it may affect its ability to pick up oxygen from the blood because the photoreceptors are right at the back of the eye, close to something called thechoroid plexus. The choroid plexus is a very dense network of blood vessels. In fact, the retina has one of the highest metabolic rates of any tissue in the body and if you affect the way at which oxygen moves out of the choroid plexus and into the photoreceptors for even a fraction of a second, they start to deliver abnormal firing activity, and you start to see these funny lights.

You might have seen this if you stand up quickly out of the bath, when you've had a hot bath. You may have noticed a similar strange wooziness, but also, you'll have noticed some perhaps funny lights in front of your eyes. That’s because your blood pressure temporarily dips when you stand up and you deprive the photoreceptors of their oxygen supply momentarily, and they respond by firing off all these funny blazes of colours. So, it’s an entoptic phenomenon secondary to physical deformation of the retina, but also probably because you're affecting the ability of the retina to grab its oxygen supply.

I used to do this ALL THE TIME as a kid. I'm glad to finally have an explanation for it.

Put together this video to document a recent project. Didn't realise until editing that I'd shot the whole thing in low resolution! Consider this a sneaky peak. High res to come. Find out more here.
