Scientists have found a way to electrically stimulate the brain using a cheap, painless, safe, and easily wearable headband so that you can perform better at… everything. It’s not sci-fi, and likely probably simpler, easier to use and more effective than you’re thinking.
Do I want or do I want?
Haven’t read an article this refreshing in a while. Here’s a quote to contextualize:
[Aldous] Huxley posited that ordinary consciousness represents only a fraction of what the mind can take in. In order to keep us focused on survival, Huxley claimed, the brain must act as a “reducing valve” on the flood of potentially overwhelming sights, sounds and sensations. What remains, Huxley wrote, is a “measly trickle of the kind of consciousness” necessary to “help us to stay alive.”
A new study by British researchers supports this theory. It shows for the first time how psilocybin — the drug contained in magic mushrooms — affects the connectivity of the brain. Researchers found that the psychedelic chemical, which is known to trigger feelings of oneness with the universe and a trippy hyperconsciousness, does not work by ramping up the brain’s activity as they’d expected. Instead, it reduces it.
Some have argued, for example, that the geometric visual hallucinations commonly seen by people on psychedelics (and by some sufferers of migraines) help reveal the architecture of the brain’s visual processing mechanism. “One hypothesis is that what you’re actually seeing is the functional organization of the visual cortex itself. The visual cortex is organized in a sort of fractal way [it repeats the same patterns in different sizes]. It’s the same way that fractals are everywhere in nature. Like tree branches, the brain recapitulates [itself],” says Carhart-Harris. “You’re not seeing the cells themselves, but the way they’re organized — as if the brain is revealing itself to itself.”
I really want to do shrooms right now.
Reading fiction can strengthen your social ties and even change your personality.
Bookworms rejoice.

Imagination as ‘seeing’: too cool.
Here’s some added visual sugar for your nightly diet: ‘dreams’ might be more common than expected simply because of how our eyes/brains are wired.
The picture above explains a lot, once you understand it, but in order to do so, you’ll need to (at least skim) read this article about ‘common visual archetypes’ as explained/ruined by science: http://countyourculture.com/2011/03/13/form-constants-visual-cortex/
Warning: nightmares of fleshless demons might ensue. Creepy shit.
