Kurzweil : "Tonegawa Lab MIT - Optogenetics | Plant false memories in the brain | Inventer le monde | Scoop.it

The phenomenon of false memory has been well-documented : In many court cases, defendants have been found guilty based on testimony from witnesses and victims who were sure of their recollections, but DNA evidence later overturned the conviction. In a step toward understanding how these faulty memories arise, MIT neuroscientists have shown that they can plant false memories in the brains of mice. They also found that many of the neurological traces of these memories are identical in nature to those of authentic memories…

Kurzweil : "Optogenetics, a 3D light switch for the brain

Kurzweil : "Optogenetics, a 3D light switch for the brain | Inventer le monde | Scoop.it

A new fiber-optic device created by MIT biologists and engineers is the first tool that can deliver 1000 precise points of light to a 3D section of living brain tissue matter smaller than a sugar cube.

This is a step forward for a technique called optogenetics, which uses gene treatments to turn individual brain cells on and off with light. Scientists can use this new 3D “light switch” to better understand how the brain works. It might also be used one day to create neural prostheses that could treat conditions such as Parkinson’s disease and epilepsy…

Adit Israël : "Vers des lunettes pour aveugles, ou les miracles de l'optogénétique

Adit Israël : "Vers des lunettes pour aveugles, ou les miracles de l'optogénétique | Inventer le monde | Scoop.it

Des chercheurs israéliens du Technion de Haïfa viennent de proposer une nouvelle approche pour redonner la vision à des personnes aveugles. Cette méthode s'applique aux personnes souffrant d'une maladie dégénérative de la rétine externe, l'une des causes majeures de perte de vue dans le monde occidental…
