We're hiring! Postdoc position to study the neural control of reaching using high-density multi-area electrophysiology. 5 years of funding, great collaborative environment. Please share with anyone who may be interested. For details, see: docs.google.com/document/d/1jU…

@SiddiquiLab congrats Tabrez!!!!

I am pleased to share our paper showing that the minimal neurexin-1 isoform Nrx1γ forms a nanoscale trans-synaptic bridge aligning presynaptic release machinery with AMPAR nanodomains, tuning synaptic transmission and behaviour. Full access at authors.elsevier.com/a/1nTlG3BtfHGo…

We would like to welcome Dr. Wendy Xin (Assistant Professor, Department of Physiology, University of Toronto), to the CPIN Program. Wendy is also a scientist at the Donald K. Johnson Eye Institute and Krembil Brain Institute at UHN.

@choekatr @McMasterU congrats!!!

I am thrilled to officially announce that I have been promoted to Associate Professor with Tenure at @McMasterU! I have so many people to thank for this incredible career milestone:

Qu'est-ce qui réveille une cellule souche neurale de son sommeil ? 🧠⏳ Une nouvelle étude menée par le Dr Armen Saghatelyan, de la Faculté de médecine de l'Université d'Ottawa, montre que les cils microscopiques qui battent sur les cellules voisines pourraient jouer un rôle clé. Points clés : ⚙️ Les forces physiques contribuent à maintenir la dormance des cellules souches. ⚡ La perturbation du mouvement des cils active les cellules souches neurales. 🌱 Des mécanismes similaires pourraient exister dans d’autres organes. Ces résultats ouvrent de nouvelles perspectives prometteuses pour la médecine régénérative, offrant de nouvelles façons de comprendre et d’exploiter potentiellement le comportement des cellules souches pour de futurs traitements. 🔬 Pour en savoir plus sur cette étude, cliquez sur le lien ici : uottawa.ca/faculte-medeci…

真夏の台湾へ！

CAN and CIHR-INMHA are very proud to announce the winners of the 2025 Brain Star awards. See all their profiles here: can-acn.org/congratulation…

@Lab_Saghatelyan congrats Armen!!!

Happy to share our article in @NeuroCellPress We show how cilia beating of ependymal cells lining the walls of brain ventricles regulate neural stem cells activation/quiescence. This work was made possible by an amazing work of trainees in the lab and wonderful collaborators 1/7

Thrilled to share our paper out today in @CellCellPress! Transcranial magnetic stimulation can effectively treat depression, but how? We uncovered cell type-specific plasticity driving these antidepressant effects 👇 cell.com/cell/fulltext/…

@YiZuoUCSC congrats!!!

New @NatureComms paper: we found a circuit that signals trial outcomes to the prefrontal cortex—and why stress makes it harder to learn from mistakes. Thanks @DailyNeuron_ for the coverage! dailyneuron.com/stress-cogniti… #zuolab #stress @MaShaorong

@Xiaochen_Sun_ impressive work!!!

Excited to share my co-first-authored work on registering in vivo Ca2+ imaging data to ex vivo transcriptomic and projection datasets, enabling the mapping of each cell’s functional coding to its genetic cell type: biorxiv.org/content/10.648….

PhD: defended :))) Started in the OR as a surgical nurse, then found my way into neuroscience, today I can finally say I HAVE DEFENDED my PhD 🎓😎 Grateful to @SChenlab for his mentorship beyond science. Thanks to my advisory committee @JCBeique, @maximewc, and Dr. Tuan Bui 🙏

The University of Ottawa's Medicine research teams earn nationally competitive grants from Brain Canada! 🧠🔬 Congratulations to Drs.
