Online now:

Distinct dendritic integration strategies control dynamics of inhibition in the neocortex

Morabito et al. observed that different neocortical interneuron (IN) populations display distinct dendritic properties by varying synaptic receptor composition and input location. These IN-specific dendritic properties enhance synaptic efficiency but are tailored to different temporal processing modes. In the visual cortex, this mechanism supports the distinct dynamics of PV- and SST-INs.

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.

I think some people hear “grants” and think that without them, scientists and government workers just have less stuff to play with at work. But grants fund salaries for students, academics, researchers, and people who work in all areas of public service. “Pausing” grants means people don’t eat.

A milestone paper for the lab. First causal demonstration of the impact of temporal information format on learning & a clear demonstration that the mouse auditory system structures sound representations very similar to what sound categorization deep networks do. www.science.org/doi/10.1126/...

A spatial code for temporal information is necessary for efficient sensory learning

The auditory system transforms temporal information in sounds into spatial information for rapid associations with decisions.
