🧪🧠 1/ The call for symposia for the @ibroorg.bsky.social World Congress 2027 is now open! The meeting will take place in Cape Town, South Africa 🇿🇦, 13–16 September 2027.
🧪 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

Absolutely delighted and incredibly proud to see my better half, Alanna Watt, appointed Dean of the Faculty of Science at McGill!!! 🎉 Also a very meaningful milestone: she is the first woman to serve as Dean of Science at McGill. A big moment for the Faculty, and a very exciting one for McGill ❤️
It is with great pleasure that we announce the appointment of Professor Alanna Watt, of the Department of Biology, as Dean of the Faculty of Science at McGill University. Her five-year renewable term will begin on May 1. Read the full announcement ➡️ mcgill.ca/x/5AH
🧪 1/ New preprint from the lab: L5 pyramidal cell tLTD requires astrocyte Ca2+ and CB1 signaling www.biorxiv.org/content/10.6... We revisit a classic STDP result in visual cortex

🧪🧠 New preprint: helping resolve a decades-long debate in synaptic plasticity NMDA receptors are central to Hebbian learning. Yet for >30 years, the existence and function of presynaptic NMDA receptors have remained controversial. 📄 doi.org/10.64898/202... 1/6

🧪 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....

Our new paper is out in Science. What is the synaptic plasticity rule in the brain, we asked. It turns out there are multiple, even within individual neurons. Congrats Jake! www.science.org/doi/10.1126/...
Distinct synaptic plasticity rules operate across dendritic compartments in vivo during learning
Synaptic plasticity underlies learning by modifying specific synaptic inputs to reshape neural activity and behavior. However, the rules governing which synapses will undergo different forms of plasti...

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! 🧪
