Recommendable! This could be a breakthrough! The operative phrase her is "without implants"!
"Scientists have created a light-responsive opsin so sensitive that even when engineered into cells deep within tissue it can respond to an external light stimulus, according to a report in Neuron yesterday (April 30). Experiments in mice and macaques showed that shining blue light on the surface of the skull or brain was sufficient to activate opsin-expressing neurons six millimeters deep."
