Optogenetics takes its next step: switching on just a few neurons makes mice hallucinate. My story for
Scientists planted a specific visual image in the brains of mice. (Coming soon: Netflix beamed directly into your brain?)
It takes the stimulation of just two neurons to induce hallucinations in the brains of mice. If that's all, why are we not hallucinating all the time?
3/3 Finally, they had a thoughtful experimental design including “tuned" & “random” populations (plus NEW tuned & random populations to test for generalization, fig 4i).
Why Are These Mice Hallucinating? Scientists Are in Their Heads: New laser technology appeared to trigger particular images in the brains of lab mice. “It’s not like a creature can tell you, ‘Oh, wow, I saw a horizontal bar,’”
