Northwestern University researchers are building social bonds with beams of light.
For the first time ever, Northwestern engineers and neurobiologists have wirelessly programmed and then deprogrammed mice to socially interact with one another in real time. The advancement is thanks to a first-of-its-kind ultraminiature, wireless, battery-free and fully implantable device that uses light to activate neurons.
This study is the first optogenetics (a method for controlling neurons with light) paper exploring social interactions within groups of animals, which was previously impossible with current technologies.
The research will be published May 10 in the journal ....
