System for control of spasticity

Grégoire Courtine, Jocelyne Bloch, Fabien Bertrand Paul Wagner, Robin Jonathan Demesmaeker, Salif Axel Komi, Karen Minassian

The present invention relates to a neuromodulation/neurostimulation system (10) for the treatment of spasticity in a mammal, said system (10) comprising: - at least one control unit (12) configured and arranged to provide stimulation data, and - at least o ...

Hyperpolarized C-13-glucose magnetic resonance highlights reduced aerobic glycolysis in vivo in infiltrative glioblastoma

Rolf Gruetter, Arnaud Comment, Cristina Ramona Cudalbu Moldovan, Bernard Lanz, Mor-Miri Mishkovsky, Jocelyne Bloch

Glioblastoma (GBM) is the most aggressive brain tumor type in adults. GBM is heterogeneous, with a compact core lesion surrounded by an invasive tumor front. This front is highly relevant for tumor recurrence but is generally non-detectable using standard ...

Principles of gait encoding in the subthalamic nucleus of people with Parkinson's disease

Morgane Laurence Burri, Grégoire Courtine, Jocelyne Bloch, Eduardo Martin Moraud, Jimmy James Ravier, Carmina Andrea Galvez Solano, Charlotte Marie Jacques Moerman

Disruption of subthalamic nucleus dynamics in Parkinson's disease leads to impairments during walking. Here, we aimed to uncover the principles through which the subthalamic nucleus encodes functional and dysfunctional walking in people with Parkinson's di ...

Walking naturally after spinal cord injury using a brain-spine interface

Cathal John Harte, Nadine Intering, Grégoire Courtine, Jocelyne Bloch, Léonie Asboth, Robin Jonathan Demesmaeker, Salif Axel Komi, Jimmy James Ravier, Henri Charles Alexandre Lorach, Carmina Andrea Galvez Solano, Grégory Didier Dumont, Edeny Baaklini, Sergio Daniel Hernandez, Thibault Jean Etienne Collin, Icare Sakr

A spinal cord injury interrupts the communication between the brain and the region of the spinal cord that produces walking, leading to paralysis(1,2). Here, we restored this communication with a digital bridge between the brain and spinal cord that enable ...

Single-cell and spatial atlases of spinal cord injury in the Tabulae Paralytica

Grégoire Courtine, Bernard Schneider, Jocelyne Bloch, Quentin Barraud, Claudia Kathe, Matthieu Pierre Gautier, Nicholas David James, Thomas Haynes Hutson, Michael Alexander Skinnider, Achilleas Laskaratos, Michael V. Sofroniew, Nicola Aldo Regazzi

Here, we introduce the Tabulae Paralytica—a compilation of four atlases of spinal cord injury (SCI) comprising a single-nucleus transcriptome atlas of half a million cells, a multiome atlas pairing transcriptomic and epigenomic measurements within the same ...

A spinal cord neuroprosthesis for locomotor deficits due to Parkinson's disease

Jean François Pierre Laurens, Auke Ijspeert, Silvestro Micera, Stéphanie Lacour, Grégoire Courtine, Marco Capogrosso, Jocelyne Bloch, Giuseppe Schiavone, Elvira Pirondini, Jordan Squair, Eduardo Martin Moraud, Léonie Asboth, Robin Jonathan Demesmaeker, Tomislav Milekovic, Jimmy James Ravier, Jean-Baptiste Mignardot, Flavio Raschella, Simon Borgognon, Alice Julie Bruel, Carmina Andrea Galvez Solano, Camille Georgette Marie Le Goff-Mignardot, Charlotte Marie Jacques Moerman, David Allenson Borton, Grégory Didier Dumont, Sergio Daniel Hernandez, Nicolò Macellari, Shiqi Sun

People with late-stage Parkinson's disease (PD) often suffer from debilitating locomotor deficits that are resistant to currently available therapies. To alleviate these deficits, we developed a neuroprosthesis operating in closed loop that targets the dor ...

Brain-spine interfaces to reverse paralysis

Grégoire Courtine, Jocelyne Bloch, Henri Charles Alexandre Lorach

OXFORD UNIV PRESS2022

A digital bridge between brain and spinal cord restores walking after paralysis

Grégoire Courtine, Jocelyne Bloch

Spinal-cord injury interrupts communication between the brain and spinal cord, leading to paralysis. An implant that decodes the brain signals that control movements and drives electrical stimulation of the spinal cord re-establishes this communication, en ...

NATURE PORTFOLIO2023

Natural and targeted circuit reorganization after spinal cord injury

Grégoire Courtine, Jocelyne Bloch, Quentin Barraud, Jordan Squair, Claudia Kathe, Matthieu Pierre Gautier, Mark Andrew Anderson, Thomas Haynes Hutson

The authors summarize changes in circuits after spinal cord injury and current strategies to target these circuits in order to improve recovery, but also advocate for new concepts of reorganizing circuits informed by multi-omic single-cell atlases. ...

Neuromodulation/neurostimulation system for controlling a respiratory function

Grégoire Courtine, Jocelyne Bloch, Léonie Asboth, Robin Jonathan Demesmaeker, Vincent Delattre, Miroslav Caban, Nicolas Hankov

The present invention relates to a neuromodulation/neurostimulation system for supporting and/or controlling a function of t he respiratory system of a patient, said function comprising a plurality of phases each involving one or more muscles. The system c ...

Implanted System for Orthostatic Hypotension in Multiple-System Atrophy

Grégoire Courtine, Jocelyne Bloch, Jordan Squair, Léonie Asboth, Robin Jonathan Demesmaeker, Grégory Didier Dumont, Nicolas Hankov, Sergio Daniel Hernandez, Suje Amir

Orthostatic hypotension is a cardinal feature of multiple-system atrophy. The upright posture provokes syncopal episodes that prevent patients from standing and walking for more than brief periods. We implanted a system to restore regulation of blood press ...

Online prediction of optimal deep brain stimulation contacts from local field potentials in Parkinson’s disease

Jocelyne Bloch, Stefano Scafa, Camille Claire Varescon

Selecting optimal contacts for chronic deep-brain stimulation (DBS) requires a monopolar review, involving time-consuming manual testing by trained personnel, often causing patient discomfort. Neural biomarkers, such as local field potentials (LFP), could ...
