Scientists control mouse neurons so that rodents see things that aren't there / Boing Boing



Scientists have used laser light to activate neurons in a mouse's brain, so that the rodents do not "see" existing lines. The technique, called optogenetics, switches neurons in and out of which it is made genetic in order to be light-sensitive. According to Science News, "The results, described online in Science on July 18, represent the first time scientists have made a specific visual perception of laboratory trickery." In this case, the mice were trained to drink water from a kiss to & quot; they saw the lines. Fan Science News:

When optogenetics first debuted 15 years ago, everyone hopes to reach this level of control over perception, and the behavior that follows, says Karl Deisseroth, a neuroscientist and psychiatrist who pioneered the technique. "It's exciting to come to this point," says Deisseroth, a researcher at Howard Hughes Medical Institute at Stanford University …

Similar approaches can make scientists other types of perceptions, such as smells, touching and flavors, says Deisseroth.
