Wireless closed-loop optogenetics across the entire dorsoventral spinal cord in mice

Stéphanie Lacour, Grégoire Courtine, Quentin Barraud, Léonie Asboth, Ileana Ozana Jelescu, Ivan Furfaro, Kyungjin Kim, Jérôme Gandar, Frédéric Pierre Gérald Michoud, Claudia Kathe

Optoelectronic systems can exert precise control over targeted neurons and pathways throughout the brain in untethered animals, but similar technologies for the spinal cord are not well established. In the present study, we describe a system for ultrafast, ...

The neurons that restore walking after paralysis

Stéphanie Lacour, Grégoire Courtine, Jocelyne Bloch, Quentin Barraud, Jordan Squair, Léonie Asboth, Katia Galan, Robin Jonathan Demesmaeker, Nicholas David James, Matthieu Pierre Gautier

A spinal cord injury interrupts pathways from the brain and brainstem that project to the lumbar spinal cord, leading to paralysis. Here we show that spatiotemporal epidural electrical stimulation (EES) of the lumbar spinal cord(1-3) applied during neurore ...
