BERLIN: A turning point for Rafael Yuste, a neuroscientist at New York’s Columbia University, came when his lab discovered it could activate a few neurons in a mouse’s visual cortex and make it hallucinate.
The mouse had been trained to lick at a water spout every time it saw two vertical bars, and researchers were able to prompt it to drink even with no bars in sight, said Yuste, whose team published a study on the experiment in 2019.
