Activity-dependent spinal cord neuromodulation rapidly restores trunk and leg motor functions after complete paralysis

Dimitri Nestor Alice Van De Ville, Silvestro Micera, Grégoire Courtine, Jocelyne Bloch, Quentin Barraud, Léonie Asboth, Robin Jonathan Demesmaeker, Nawal Noëlle Kinany, Miroslav Caban, Sergio Daniel Hernandez

Epidural electrical stimulation (EES) targeting the dorsal roots of lumbosacral segments restores walking in people with spinal cord injury (SCI). However, EES is delivered with multielectrode paddle leads that were originally designed to target the dorsal ...

Recruitment of upper-limb motoneurons with epidural electrical stimulation of the cervical spinal cord

Stéphanie Lacour, Grégoire Courtine, Giuseppe Schiavone, Nicholas David James, Simon Borgognon, Henri Charles Alexandre Lorach, Florian Dylan Fallegger, Nathan Antoine Greiner

Epidural electrical stimulation (EES) of lumbosacral sensorimotor circuits improves leg motor control in animals and humans with spinal cord injury (SCI). Upper-limb motor control involves similar circuits, located in the cervical spinal cord, suggesting t ...

Spatiotemporal Maps of Proprioceptive Inputs to the Cervical Spinal Cord During Three-Dimensional Reaching and Grasping

Auke Ijspeert, Shravan Tata Ramalingasetty, Marco Capogrosso, Nathan Antoine Greiner, Beatrice Barra, Pierre Charles Marie Kibleur, Sara Conti

Proprioceptive feedback is a critical component of voluntary movement planning and execution. Neuroprosthetic technologies aiming at restoring movement must interact with it to restore accurate motor control. Optimization and design of such technologies de ...

Refinements of hybrid neurophysical volume conductor models and application to study epidural electrical stimulation of the cervical spinal cord

Nathan Antoine Greiner

After spinal cord injury (SCI), the communication between the brain and spinal neural circuits below the lesion is disrupted, leading to paralysis. Epidural electrical stimulation (EES) of the lumbosacral spinal cord has been shown to restore locomotion an ...

Advantages of soft subdural implants for the delivery of electrochemical neuromodulation therapies to the spinal cord

Stéphanie Lacour, Marco Capogrosso, Grégoire Courtine, Eduardo Martin Moraud, Pavel Musienko, Ivan Rusev Minev, Nikolaus Wenger, Jérôme Gandar, Polina Shkorbatova, Nathan Antoine Greiner

Objective. We recently developed soft neural interfaces enabling the delivery of electrical and chemical stimulation to the spinal cord. These stimulations restored locomotion in animal models of paralysis. Soft interfaces can be placed either below or abo ...
