Some good news. A wonderful postdoc in the lab landed her dream job! And that means we are looking for postdocs!

Keeping up with the literature is essential. But so is devoting time to developing your own scientific ideas, writes @sjo09. thetransmitter.org/craft-and-care…

New manuscript published! ✍️👀 Concept neurons evolve from index neurons through overlapping memories. Check it out here: cell.com/trends/cogniti… 1/15

This month’s "Launch" newsletter features an essay by @sjo09 on the importance of reading (but not too much), Q&As with Ana Gonzalez-Rueda and @DrewKesner about their new labs, the latest job openings & more. Subscribe to receive the newsletter each month: thetransmitter.org/newsletters-al…

My inspiring colleague @GreggNeuroLab was diagnosed with terminal stage breast cancer, a rare disease in males. He came up with a way to combat it and wants to change the way cancer is treated! 🙌statnews.com/2025/06/17/can…

Three #UofT faculty members have been appointed University Professors, a prestigious designation that represents the university’s highest & most distinguished academic rank. 🏫 uoft.me/bDa

New preprint! Since we discovered that histone variants regulate memory, we wondered if histone H2A.Z contributes to Alzheimer's. Using human brains and 5xFAD mice, we found that it depends on if you're male or female. Summary below. biorxiv.org/cgi/content/...

The 2025 GRC on Cannabinoid Function in the CNS: Cannabinoid Neurobiology: Bridging Basic Science, Big Data, Biomarkers and Bedside Applications Across the Lifespan final program is here! Spots are going fast! Register soon for trainee talks! RT please! grc.org/cannabinoid-fu…

I’m excited to share a new paper from the lab. The study led by Xiaowei Gu reveals how the mPFC encodes complex emotional memories, using an internal model to infer emotional associations and memories via projections to the amygdala rdcu.be/el19t nature.com/articles/s4158…

Join us for the CAN 2025 Public lectures, titled: Neuroscience of memory and tools for making our memories stronger, featuring two memory experts from Toronto: Drs. Sheena Josselyn and Morgan Barense. The event will be hosted by Dr. Iva Zovkic can-acn.org/meeting-2025/c…

🏆ECNP is pleased to announce the winner of the 2025 ECNP Neuropsychopharmacology Award: @carmensandi10, Switzerland, for her groundbreaking research on the #neurobiology of #stress and #anxiety. Congratulations! More info➡️ecnp.eu/ena-winner2025/ #ECNP2025 #ECNP #BrainResearch

Excited to share the sequel to our 2022 paper! In this follow-up, we show that the stable head direction (HD) signals we reported in blind mice rely on stereo olfaction—that is, the comparison of odor info. between the two nostrils. Link: nature.com/articles/s4146… 🧵highlights

⭐Christmas highlight in Cell Research! @sjo09 and I address the exciting idea that learning-associated astrocytes become essential members of a memory engram ensemble, challenging the neuron-centric view of memory function. Shoutout to @m_r_williamson! doi.org/10.1038/s41422…

A Christmas Story is a must-watch for many during the Christmas season. While set in Indiana, there are actually quite a few Canadian connections with this film. Let's learn more about them :) 🧵1/9

🎉Two seismic things happened in 1989: 1️⃣Taylor Swift was born 🎂 2️⃣The Human Genome Project was about to be born 🧬 As Dr. Eric Green said during #GairdnerScienceWeek: both "changed the world forever." Happy birthday @taylorswift13 #GairdnerAwards #Genomics
