Artificial pieces of brain use light to communicate with real neurons

Researchers at The University of Tokyo, University of Bordeaux and at Ikerbasque have created a way for artificial neuronal networks to communicate with biological neuronal networks. The new system converts artificial electrical spiking signals to a visual pattern than is then used to entrain the real neurons via optogenetic stimulation of the network. This advance will be important for future neuroprosthetic devices that replace damages neurons with artificial neuronal circuitry.
