How to restore #motor function after #stroke? This study shows in mice that a combination of #RoboticRehabilitation & non-invasive gamma band #neuromodulation improves motor recovery by restoring movement-related oscillations & parvalbumin #interneuron dynamics @plosbiology.org 🧪 plos.io/4n7QJng
Enduring reduction of resting state functional connectivity (FC) of parvalbumin-positive interneurons (PV-INs) after stroke. Top left: Experimental timeline, with the cranial optical window implanted one week before the first imaging session. Imaging time point at −1 (PRE), 2, 5, 8, 14, 21, and 28 days after stroke. Top right: Left, representative image sequence of cortical PV-IN activity before stroke. The black dot indicates bregma. L: lateral; M: medial; R: rostral; C: caudal (Scale bar, 1 mm). Right, wide-field calcium imaging field-of-view aligned with the surface of the Allen Institute Mouse Brain atlas. The green area on the left hemisphere locates the damaged region. Yellow squares represent cortical areas defined in both left (L, contralesional) and right (R, ipsilesional) hemispheres. Red dot indicates bregma (Scale bar, 1 mm). Middle row: Pairwise Pearson’s correlation coefficients of cortical activity were visualized as averaged correlation matrices for each imaging time point after hemodynamic correction. Bottom row: Network diagrams of statistically significant FC alterations after 2, 5, 8, 14, 21, or 28 days from injury. Blue and red lines denote significant hyper-correlation and hypo-correlation compared to prestroke values, respectively.

🤯 👁️ Did you know the primary visual cortex tracks head movements even in complete darkness?

Guy Bouvier and colleagues managed to decode multiple head movement variables in V1 without light in the room, and discovered two distinct brain sources delivering these signals!

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.

In brief, we explored in silico how cortical slow waves are shaped by both external inputs and intrinsic properties of neuronal populations.

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.

Du poids indéniable de l'école dans la production des inégalités genrées face aux mathématiques

"Rapid emergence of a maths gender gap in first grade"
par P. Martinot et al.

Une étude sur 3 million d'enfants en France (!!!) qui va faire du bruit

#LaRAC @nature.com
www.nature.com/articles/s41...
Preventing gender disparities in mathematics is a worldwide preoccupation1,2. In infancy and early childhood, boys and girls exhibit similar core knowledge of number and space3,4,5,6,7,8. Gender disparities in maths are, therefore, thought to primarily reflect an internalization of the sociocultural stereotype that ‘girls are bad at maths’. However, where, when and how widely this stereotype becomes entrenched remains uncertain. Here, we report the results of a 4-year longitudinal assessment of language and mathematical performance of all French first and second graders (2,653,082 children). Boys and girls exhibited very similar maths scores upon school entry, but a gender gap in favour of boys became highly significant after 4 months of schooling and reached an effect size of about 0.20 after 1 year. These findings were repeated each year and varied only slightly across family, class or school type and socio-economic level. Although schooling correlated with age, exploiting the near-orthogonal variations indicated that the gender gap increased with schooling rather than with age. These findings point to the first year of school as the time and place where a maths gender gap emerges in favour of boys, thus helping focus the search for solutions and interventions. Ecart de genre en maths à T1 (début CP), T2 (janvier CP) et T3 (début CE1) en fonction de l'âge des enfants en mois lors de la passation du test, pour les quatre années de cohorte (d de Cohen). Étant donné que l'entrée à l'école est strictement déterminée par la date de naissance, les enfants du même âge peuvent différer dans leur durée de scolarisation (couleurs et lignes de régression). Quel que soit l'âge auquel ils ont passé le test, les enfants présentaient un écart minime ou nul entre les sexes en mathématiques à T1, mais l'effet s'est accentué après 4 mois (T2) et 12 mois (T3) de scolarisation.

The "rubber hand illusion" in mice... @lucestebanez.bsky.social &co use automated videography to show that mice display quantifiable behavioral markers of the embodiment of an #ArtificialLimb, opening the door to future research into human #BodyOwnership disorders @plosbiology.org 🧪 plos.io/4jHsESn
The rubber-hand illusion was translated to the mouse model. Just like in humans, embodiment in mice can be achieved by brushing the real forelimb of the mouse and the artificial limb (yellow) in synchrony to generate matching visual and touch percepts. This study suggests that as the mouse looks at the artificial limb, it perceives it as its own limb, and feels threatened if the artificial limb is threatened. Image credit: Luc Estebanez.
