Very cool! Five minutes of this felt strangely soothing in my head, after a few nights of not enough sleep. Being able to set a max duration would be neat, in case it's unsafe to lose track of time and let the pattern run for too long? Classic outdated comment BTW ;) setInterval(flickerImage, 250); // 8hz

When I open the page, the image rotates for about ten seconds then vanishes. How do you watch it for five minutes? What did I do wrong?

There have been a couple of papers [1] that can induce this process while awake using particular image patterns as confirmed in an MRI. I think the NIH confirmation is running behind in the science, independent research is quite a bit ahead of them. I came across the paper on this last year and implemented a very simple page with the parameters they used [2]. There is a number of disease models that show reduced or n…

This is some amazing work; and it also raises my belief that a Langford Basilisk is neurologically possible by about 25%

It's possible. But only for the brains of people with severe or undertreated epilepsy of carefully selected varieties. You can trigger a potentially fatal seizure by showing them an appropriately stimulating image. Which likely was a known concept to the author of the story. For the rest of us the negative feedback along the optical axis puts a stop to such shenanigans.

“Other studies have suggested that the glymphatic system may be most active during sleep.” Not only that but also the right sleeping position is relevant here. I don’t recall the scientist but he studied primates and their natural sleeping position, exactly this position also opens up the channels for the cerebrospinal fluid to flush the accumulated brain waste.

Do you recall which position?
