Holographic Lasers Make Mice See False Images, Raising Ethical Alarms
Why in news: Neuroscientist Rafael Yuste demonstrated using holographic lasers to implant false visual stimuli into mice brains, sparking a debate on 'neurorights' and mental privacy.
Researchers at Columbia University used holographic lasers to activate specific neurons in the visual cortex of mice. By 'playing' images directly on the cortex, they successfully manipulated the mice's behavior (e.g., drinking or stopping) without any external visual stimuli.
