Le 29 septembre 2026 – 12h30 – IPNP RDC-Cafétéria – ou par Zoom

Sclérose en plaques : remyéliniser grâce à l’activité électrique

Pr Céline Louapre, Sorbonne Université, Hôpital Pitié-Salpétrière

Dr Maria Cecilia Angulo, CNRS, INSERM U1266 Institut de Psychiatrie et Neurosciences de Paris, Université Paris Cité

Les 12h30 de la recherche offre un espace d’échanges et de rencontres entre cliniciens et chercheurs autour de thématiques formant autant de priorités et d’axes possibles de recherche pour le GHU Paris et L’Institut Neurosciences Cognition. L’objectif est la mise en place, in fine, de nouveaux axes de recherche translationnelle. A chaque session, un professionnel présentera la thématique pendant 20 minutes, suivie de 40 minutes d’échanges avec les participants.

Cet évènement sera coanimé par Nicolas Panayotis, chercheur au SPPIN, et Diana Zala, chercheuse à l’IPNP.

Neural circuits exhibit complex spatiotemporal patterns of activity during behavior. Understanding how these patterns of activity determine behavior is a fundamental problem in neuroscience and remains a major challenge due to the complexity of spatiotemporal dynamics and difficulties in access. The ability to measure and manipulate activity in genetically defined sets of neurons using optogenetics has provided a powerful new tool for establishing causal links between neural activity and behavior.

During the conference and lab visit, we will discuss optical approaches that allow the measurement of neural activity and the manipulation of the same neurons. This approach allows activity in neural circuits to be read and written with cellular resolution during behavior. We will describe the power, limitations, and potential of this approach, and discuss how it can be used to solve many important problems in neuroscience, including how this research can be transformed to inform therapies for neural disorders.

We look forward to welcoming you at Le Piano Vache for presentations by a fantastic line-up of neuroscientists from across Île-de-France. The new cycle will feature two scientists from the Saints-Pères campus : Claire Sergent (INCC) and Desdemona Fricker (SPPIN). “

From now on, seminars will begin at 5:30 pm, followed by time for informal discussions and socializing. As always, a complimentary beverage will be provided for all attendees.

We would be very grateful if you could help us spread the word within your institution and invite your colleagues, students and post-docs. A poster for printing is available [here].

We warmly thank DIM C-BRAINS for supporting Neural Networking Night.

We look forward to seeing you there!

L’équipe 8 “Orientation & Coordination” organise un événement de médiation scientifique autour des Neurosciences, le 22-28 Septembre 2025, à la Capitainerie de l’Isle, 26 rue Chanoinesse, 75004 Paris.

Plongez dans l’univers fascinant de la recherche sur le cerveau et de l’art lors de notre événement “Regards Croisés”. C’est une invitation à explorer les mystères du système d’orientation spatiale du cerveau à travers une fusion unique de science et d’art.

L’exposition est conçue en collaboration avec l’artiste Parisienne, Sophie Sainte-Marie-Heim, qui crée des représentations abstraites de cellules cérébrales et de circuits neuronaux impliqués dans l’orientation spatiale.

Come for the art, stay for the science.

Keren Zahlenchuck is going to rejoin SPPIN’s team “Biophysics of the brain” (Oheim, https://www.sppin.fr/) from 1 September onwards. Keren is the recipient of an EMBO short term fellowship and will be working with Brieuc Chauvin, Hugo Touja and Martin Oheim on new strategies to keep light-sheets thin and well-defined over large propagation distances (fields of view). Her work will further strengthen SPPIN’s traversal axis “Multi-scale neuroanatomy” (see https://www.sppin.fr/multiscale/). Keren is a physics PhD student from Alon Bahabad’s lab at TAU and she is a specialist in advanced beam shaping strategies.

Experimental neuroscience, as we know it today, is largely building on techniques that were originally developed in very diverse communities including non-linear optics, photochemistry, or light-shaping techniques. What if we bring together leading actors in contemporary topics with molecular and cellular neurobiologists to offer a friendly, open-minded and curiosity-driven emulsion of ideas? OMNI-TOOLS aims at bringing together disjunct communities from very timely, fundamental quantum optics to spatial genomics. The idea is to see if contemporary, latest developments in optics can create an immediate impact in (neuro-) biological applications. We have five years to find out.

On Monday 23/9, the SPPIN proudly hosted the kick-off meeting of the CNRS IRN “OMNI-TOOLS” international research network. 

OMNI-TOOL is co-funded by CNRS Biology and CNRS Physics in collaboration with our israeli partner universities. More infos on this IRN is found on the project website: https://www.sppin.fr/omni-tools/
