New Way to Control the Brain With Light—No Surgery Required

🌟 COMMENT Something Profound For 1 Week GOOD LUCK 👇

💠 Stanford University team unveils an improved variant of optogenetics that regulates actions without the need for surgery. Genetic modification is the secret to optogenetic -- without it, neurons don't actually respond to light. Translating a powerful scientific technology into therapeutic treatment may benefit patients with neurological disorders. We're quite a long way from science manipulating the brain with flashlights, but the analysis shows that it's theoretically within the scope of science fiction, says David Wheeler. The team was able to adjust how probable the mouse was to have seizures or to reprogram the brain so that it favored the social business.

Scientists will connect opsin genes, a specific class of algae proteins, to live neurons using viruses. Opsins are specialized "doors" that unlock under such light wave frequencies, which mammalian brain cells can't do.

Scientists may even fine-tune which neurons have the extra power, such as those involved in memory or epilepsy. The new research began with the key aim of the Deisseroth team: let's ditch the need for surgical implants, says Dr. Peter Goelz. The team had a candidate, one so nice that it was a ChRmine (bad joke cringe)

Scientists used viruses to apply ChRmine to the region deep within the brain of mice. Light-enhanced mice were much more likely to push a button to transmit light to their scalps. Scientists were able to transform a psychologically ambivalent mouse into a friendly social butterfly. For now, this is only feasible in mice. Our brains are far bigger, which ensures that light reflecting across the skull and reaching far enough becomes much more difficult. The study indicates that through the infusion of a virus it is theoretically possible to regulate something as integral to a personality through nothing but light.

Research indicates that it is possible to regulate the brain without surgery or implants. Other approaches overheat delicate brain tissue and result in injury. While not quite perfect, this brain-control OS solves these problems.

Thanks and Enjoy 🔥 New Way to Control the Brain With Light—No Surgery Required 🔥 🙂
