Biomaterials. Electronic dura mater for long-term multimodal neural interfaces

Tomislav Milekovic, Léonie Asboth, Jérôme Gandar, Nicolas Vachicouras, Stéphanie Lacour, Arthur Edouard Hirsch, Silvestro Micera, Grégoire Courtine, Nikolaus Wenger, Ivan Rusev Minev, Quentin Barraud, Simone Ellen Joze Duis, Eduardo Martin Moraud, Pavel Musienko, Marco Capogrosso, Natalia Pavlova

The mechanical mismatch between soft neural tissues and stiff neural implants hinders the long-term performance of implantable neuroprostheses. Here, we designed and fabricated soft neural implants with the shape and elasticity of dura mater, the protectiv ...

Closed-loop neuromodulation of spinal sensorimotor circuits controls refined locomotion after complete spinal cord injury

Silvestro Micera, Grégoire Courtine, Nikolaus Wenger, Stanisa Raspopovic, Marco Bonizzato, Eduardo Martin Moraud, Pavel Musienko

Neuromodulation of spinal sensorimotor circuits improves motor control in animal models and humans with spinal cord injury. With common neuromodulation devices, electrical stimulation parameters are tuned manually and remain constant during movement. We de ...

Undirected compensatory plasticity contributes to neuronal dysfunction after severe spinal cord injury

Grégoire Courtine, Janine Beauparlant, Lucia Florinda Friedli Wittler, Rubia van den Brand, Quentin Barraud, Pavel Musienko

Severe spinal cord injury in humans leads to a progressive neuronal dysfunction in the chronic stage of the injury. This dysfunction is characterized by premature exhaustion of muscle activity during assisted locomotion, which is associated with the emerge ...

A real-time platform for studying the modulatory capacity of epidural stimulation after spinal cord injury

Jérôme Gandar, Silvestro Micera, Grégoire Courtine, Nikolaus Wenger, Eduardo Martin Moraud, Pavel Musienko

Epidural electrical stimulation (EES) showed promises to improve standing and walking after neurological disorders. To date, EES has been delivered continuously, although time-dependent stimulations would likely be more efficient to activate specific subse ...

A Computational Model for Epidural Electrical Stimulation of Spinal Sensorimotor Circuits

Silvestro Micera, Grégoire Courtine, Nikolaus Wenger, Stanisa Raspopovic, Janine Beauparlant, Pavel Musienko, Marco Capogrosso

Epidural electrical stimulation (EES) of lumbosacral segments can restore a range of movements after spinal cord injury. However, the mechanisms and neural structures through which EES facilitates movement execution remain unclear. Here, we designed a comp ...

Spinal and Supraspinal Control of the Direction of Stepping during Locomotion

Pavel Musienko

Most bipeds and quadrupeds, in addition to forward walking, are also capable of backward and sideward walking. The direction of walking is determined by the direction of stepping movements of individual limbs in relation to the front-to-rear body axis. Our ...

Versatile robotic interface to evaluate, enable and train locomotion and balance after neuromotor disorders

Grégoire Courtine, Lucia Florinda Friedli Wittler, Rubia van den Brand, Pavel Musienko

Central nervous system (CNS) disorders distinctly impair locomotor pattern generation and balance, but technical limitations prevent independent assessment and rehabilitation of these subfunctions. Here we introduce a versatile robotic interface to evaluat ...
