Engineers at the University of New South Wales (UNSW Sydney) demonstrated an approach to measure neural activity using light. The team’s optical sensors, called optrodes, achieved accurate registers of the neural impulses traveling along a nerve fiber in a living animal.

According to the team, optrodes could provide a more comprehensive interface between the nerves and neural prosthetics than traditional electrodes.

“The real advantage of our approach is that we can make this connection very dense in the optical domain and we don’t pay the price that you have to pay in the electrical domain,” said professor François Ladouceur.

According to Ladouceur, optrode technology resolves several...
