3/4 As learning progressed, the mice learned to coordinate the prosthesis movements across dimensions, and they managed to consolidate a dominant prosthesis trajectory that led to rewards.
Average dominant movement of the prosthesis leading to a rewarded lick. Left: along dimension 1 of the control space. Right: dimension 2. Light curves: individual movements during one session. Thick curve: average over the session.

2/4 Our prosthesis can perform movements in a 3D space next to the body of the mice, that control it via a chronic invasive brain-machine interface. We show that the mice can drive it in a 2D subspace, while some mice managed to control it also in a 3D space.
Left: 2D control subspace. Each dimension is driven by the modulation of one of the neurons recorded in M1. Right: average learning curve, in terms of licks that provided water to the mouse.

1/4 Today we introduce the first upper limb prosthesis for the mouse model, controlled by a brain-machine interface! We show that mice can control this prosthesis via a brain-machine interface to solve a rewarded task.
Left: the upper-limb prosthesis can collect water from a tank, and bring it close to the mouth. Right: skeleton of the prosthesis with 4 DOF. THis prosthesis relies on Bowden cables.

🚨 New preprint + thread 🧵
We've gone back to studying motoneuron control principles and their applications & here's paper #1:

A proof-of-concept study showing that people with tetraplegic spinal cord injury can control up to 2DoF from a single intramuscular implant

Never thought I’d see the day when LinkedIn is the biggest driver of engagement in our papers, but we live in some strange times.

6/6 This is all thanks to the incredibly talented and passionate Anton Dogadov, who carried this whole study!

Thanks for feedback on our first version of the paper from @gbouvier.bsky.social vier.bsky.social‬ at @neuropsi.bsky.social, Jean-François Léger @ibensens.bsky.social and many others!

5/6 During cortical wave generation, the response to the movement was reshaped, and lost its relation to limb amplitude, likely being processed to match the task instead.
lucestebanez.bsky.social
4/6 Importantly, limb movements were likely required to trigger rewardable waves, but were only successful when the cortex was in the specific, suppressed state.
lucestebanez.bsky.social
3/6 We have now gone much further, and show that learning this task triggers a reshaping of the cortical dynamics, including a strong suppression of activity before rewardable wave.

2/6 One year ago, we showed that mice can learn to guide mesoscale cortical of the somatosensory cortex from a start to a target area to obtain rewards.
lucestebanez.bsky.social
1/6 We have a new/updated preprint out, led by Anton Dogadov, demonstrating operant conditioning of large cortical waves over mouse S1 thanks to a mesoscale GCamp6 brain-machine interface!

I'm excited to share my latest publication! 🚨
Global and local nature of cortical slow waves:
www.cell.com/iscience/ful...

In brief, we explored in silico how cortical slow waves are shaped by both external inputs and intrinsic properties of neuronal populations.
Global and local nature of cortical slow waves
Explaining the macroscopic activity of a neuronal population from its microscopic properties poses a great challenge, not just because of the many local agents that play a role, but due to the impact ...

Octopuses fall for the “rubber arm” illusion, just like us.

Two voltage imaging studies in two days using ASAP fluorescent indicators.

First, visualizing electrical brain waves with ASAP3, in Cell. Free link below. Though recorded by EEG for 100 years, how brain waves arise from different neuron types has been unclear.

How does the brain integrate artificial body extensions? Using a custom-built finger-extending exoskeleton, we show that wearable augmentations are quickly integrated into body representation, with proprioceptive space adapting to the device’s structure and function.

C'est notre grande tristesse d'annoncer le décès de Heather McLean, Maitresse de Conférence en neuroscience à @univparissaclay.bsky.social, chercheuse à @neuropsi.bsky.social.
Notre chère collègue et amie, Heather McLean, nous a quittés le 16 juin 2025, après s’être battue comme une lionne, avec beaucoup de courage et de détermination, contre le cancer. Canadienne de naissance, elle est arrivée en France en 1992 pour effectuer un postdoctorat dans le laboratoire de Jean Champagnat à Gif-sur-Yvette, où elle a étudié les réseaux de neurones impliqués dans les rythmes respiratoires. Après un second postdoctorat dans l’équipe de Yehezkel Ben-Ari en 1998, elle a été recrutée comme maître de conférences dans notre université. Elle y a enseigné la physiologie et les neurosciences avec passion, dynamisme et bonne humeur. Elle s’est également beaucoup investie dans la formation des professeurs des écoles en étant tout d’abord responsable d’un parcours dédié au sein de la Licence Sciences de la Vie, puis responsable de la Licence Sciences, Enseignement, Médiation. Heather McLean a contribué en première ligne à l'internationalisation des formations de l’Université Paris-Saclay, en tant que coordinatrice Erasmus+ pour le service des relations internationales, ainsi qu’en tant que directrice adjointe déléguée aux relations internationales de la graduate school Life Sciences and Health.
 
Parallèlement, Heather a mené des recherches sur les récepteurs métabotropiques au glutamate et à l’adénosine dans le cortex cérébelleux, dans l’équipe d’Hervé Daniel. En 2020, elle a rejoint l’équipe de Valérie Doyère où elle a développé une thématique centrée sur l’étude des effets de la manipulation des circuits neuronaux sur l’apparition d'états anxieux et de peurs à l’adolescence. Son HDR, intitulée From Synapses to Cognition, reflète bien son parcours : un véritable voyage au cœur du cerveau et au sein de NeuroPSI. 
 
Heather McLean était très appréciée de ses collègues et des étudiant·e·s envers qui elle se montrait toujours à l’écoute et bienveillante. Sa bonne humeur, son esprit collaboratif et sa curiosité nous manqueront à toutes et à tous, énormément.
