Hypothalamic deep brain stimulation augments walking after spinal cord injury

Grégoire Courtine, Jocelyne Bloch, Quentin Barraud, Léonie Asboth, Mark Andrew Anderson, Katia Galan, Robin Jonathan Demesmaeker, Nicholas David James, Matthieu Pierre Gautier, Nicolas Hankov

A spinal cord injury (SCI) disrupts the neuronal projections from the brain to the region of the spinal cord that produces walking, leading to various degrees of paralysis. Here, we aimed to identify brain regions that steer the recovery of walking after i ...

Early intensive rehabilitation reverses locomotor disruption, decrease brain inflammation and induces neuroplasticity following experimental Cerebral Palsy

Grégoire Courtine, Yohan Van de Looij, Quentin Barraud, Laetitia Danielle Philippine Baud

Background: Cerebral Palsy (CP) is a major cause of motor and cognitive disability in children due to injury to the developing brain. Early intensive sensorimotor rehabilitation has been shown to change brain structure and reduce CP symptoms severity. We c ...

Recovery of walking after paralysis by regenerating characterized neurons to their natural target region

Grégoire Courtine, Bernard Schneider, Jocelyne Bloch, Quentin Barraud, Jordan Squair, Mark Andrew Anderson, Katia Galan, Nicholas David James, Matthieu Pierre Gautier, Laetitia Danielle Philippine Baud

Axon regeneration can be induced across anatomically complete spinal cord injury (SCI), but robust functional restoration has been elusive. Whether restoring neurological functions requires directed regeneration of axons from specific neuronal subpopulatio ...

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 ...

Cortico–reticulo–spinal circuit reorganization enables functional recovery after severe spinal cord contusion

Grégoire Courtine, Bernard Schneider, Quentin Barraud, Léonie Asboth, Mark Andrew Anderson, Lucia Florinda Friedli Wittler, Laetitia Danielle Philippine Baud, Polina Shkorbatova, Janine Beauparlant, Galyna Pidpruzhnykova

Severe spinal cord contusions interrupt nearly all brain projections to lumbar circuits producing leg movement. Failure of these projections to reorganize leads to permanent paralysis. Here we modeled these injuries in rodents. A severe contusion abolished ...

Spatiotemporal neuromodulation therapies engaging muscle synergies improve motor control after spinal cord injury

Silvestro Micera, Stéphanie Lacour, Grégoire Courtine, Quentin Barraud, Jocelyne Bloch, Marco Capogrosso, Eduardo Martin Moraud, Pavel Musienko, Nikolaus Wenger, Natalia Pavlova

Electrical neuromodulation of lumbar segments improves motor control after spinal cord injury in animal models and humans. However, the physiological principles underlying the effect of this intervention remain poorly understood, which has limited the ther ...

A neurorobotic platform for locomotor prosthetic development in rats and mice

Grégoire Courtine, Joachim von Zitzewitz, Léonie Asboth, Nicolas Francis Fumeaux, Laetitia Danielle Philippine Baud

Objectives. We aimed to develop a robotic interface capable of providing finely-tuned, multidirectional trunk assistance adjusted in real-time during unconstrained locomotion in rats and mice. Approach. We interfaced a large-scale robotic structure actuate ...

Rehabilitative Soft Exoskeleton for Rodents

Silvestro Micera, Grégoire Courtine, Jamie Paik, Eduardo Martin Moraud, Joachim von Zitzewitz, Sophie Marie Marthe Wurth, Rubia van den Brand, Juan Manuel Florez Marin, Laetitia Danielle Philippine Baud, Manan Kishore Shah

Robotic exoskeletons provide programmable, consistent and controllable active therapeutic assistance to patients with neurological disorders. Here we introduce a prototype and preliminary experimental evaluation of a rehabilitative gait exoskeleton that en ...

Lack of additive role of ageing in nigrostriatal neurodegeneration triggered by alpha-synuclein overexpression

Grégoire Courtine, Laetitia Danielle Philippine Baud, Isabel Laura Vollenweider

Introduction: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons as well as the presence of proteinaceous inclusions named Lewy bodies. alpha synuclein (alpha-syn) is a major constituent o ...
