At #FENS2026? Come see my PhD student Sabine Rannio’s poster Tuesday morning! Distinct pre- and postsynaptic NMDAR pools govern different forms of cortical plasticity. 📍PS01-07AM-021, 09:30–13:00 I’ll be around too, so come say hi! Next, off to Tuscany for the Synaptic Transmission GRC.

🧪 1/ Our review “The 3-Body Problem: How Astrocytes May Govern Plasticity” is now out in The Neuroscientist. We explore the idea that astrocytes help determine when & where synaptic plasticity is permitted, reframing the credit assignment problem in biological circuits. doi.org/10.1177/1073...

The 3-Body Problem: How Astrocytes May Govern Plasticity - Airi Watanabe, Connie Guo, P. Jesper Sjöström, 2026

Learning and memory were long thought to be the domains of neurons and neural networks, but recent work across brain systems has established that astrocytes pla...

🧪 Excellent review unpacking where Hebbian and homeostatic plasticity converge, and where they diverge. A clear framework for reconciling synaptic stability with learning-related change. Delighted to see this in the 'Diversity of the Plasticitome' research topic.

Happy to share new review from Harshit in the lab with Kira from Tim Kennedy's lab in Montreal on shared and divergent mechanisms in Hebbian and homeostatic plasticity. We hope it will be helpful to the community - was a lot of fun to write! www.frontiersin.org/articles/10....

🧪 The Sjöström Lab in Montreal is looking for a postdoc! We study cortical circuits, synaptic plasticity, and NMDAR signalling using custom 2-photon microscopy and optogenetics. We seek candidates with strong patch-clamp and/or 2-photon imaging expertise, and a relevant publication track record.

We are looking for an outstanding postdoctoral researcher to join our team at McGill University. The Sjöström lab studies neocortical circuits, with a focus on synaptic plasticity, NMDA receptor signaling, 2-photon optogenetics, and advanced 2-photon imaging. We are particularly interested in candidates with strong expertise in whole-cell patch-clamp electrophysiology and/or 2-photon imaging, and a solid track record of relevant publications.
Applicants should be experienced with whole-cell recordings and/or cutting-edge imaging approaches. Responsibilities will include performing experiments, analyzing and presenting data locally and internationally, writing manuscripts, and occasionally mentoring junior lab members.
Our lab is based at the Research Institute of the McGill University Health Centre, in vibrant, multicultural Montreal—a city that offers exceptional quality of life. McGill and its neighbouring universities form one of the most dynamic neuroscience communities in the world.
For examples of our current directions, see:
•	Chou et al The Innovation 2025, www.cell.com/the-innovation/fulltext/S2666-6758(24)00173-5
•	Wong et al Neuron 2024, www.cell.com/neuron/fulltext/S0896-6273(23)00767-5
The position is fully funded with a competitive salary. Candidates are also expected to apply for external funding, for which we provide strong support. Opportunities are available for both Canadian and international applicants.
To apply, please send a Letter of Intent, CV, brief research statement, and contact information for three referees to Dr. Jesper Sjöström (jesper.sjostrom@mcgill.ca). In the subject line, include "Postdoc" followed by your name.
Application deadline: July 31, 2025.

McGill University is committed to diversity and equity in employment.

As a rule, cells that fire together wire together, but some synapses disobey this rule, notably hippocampal basket cells, BCs, have anti-Hebbian plasticity. We wondered if this was true in neocortex as well, and it turns out it is, suggesting a general principle! 🧪
