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

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

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 ...

Automatic clustering of spinal reflexes evoked by epidural electrical stimulation of the cervical spinal cord in non-human primates

Giuseppe Schiavone, Stéphanie Lacour, Grégoire Courtine, Marco Capogrosso, Sara Conti, Beatrice Barra, Katie Zhi Zhuang, Jocelyne Bloch

Epidural electrical stimulation of the spinal cord elicits motor responses by recruiting large sensory afferents in the posterior roots. Divergence of excitatory inputs provided by these fibers generates a variety of shapes, latencies and amplitudes in the ...

Microneurography as a tool to develop decoding algorithms for peripheral neuro-controlled hand prostheses

Silvestro Micera, Stanisa Raspopovic, Marco Capogrosso, Francesco Maria Petrini, Jacopo Rigosa, Alessandra Pampaloni, Beatrice Barra

Background:The usability of dexterous hand prostheses is still hampered by the lack of natural and effective control strategies. A decoding strategy based on the process-ing of descending efferent neural signals recorded using peripheral neural interfaces ...

Selective Recruitment of Arm Motoneurons in Nonhuman Primates Using Epidural Electrical Stimulation of the Cervical Spinal Cord

Giuseppe Schiavone, Camille Roux, Stéphanie Lacour, Grégoire Courtine, Marco Capogrosso, Beatrice Barra, Jocelyne Bloch

Recovery of reaching and grasping ability is the priority for people with cervical spinal cord injury (SCI). Epidural electrical stimulation (EES) has shown promising results in improving motor control after SCI in various animal models and in humans. Nota ...
