#OptoGRC2026 is just around the corner! We are thrilled for this year's program, including keynote speakers @OferYizhar, @sjo09, and @yusterafa. Applications to attend are still being accepted through April 12. Register now👇 grc.org/optogenetic-ap…

We are officially less than two months away from #OptoGRC2026! 🤩 Submit your abstract by March 22 to be considered for a talk. Attendee applications are open until April 12, but we recommend applying soon before spots fill up! Register: grc.org/optogenetic-ap…

As we sleep, our bodies may be quiet and largely immobile—but our brains are highly active. A special issue summarized recent insights into the basic mechanisms underlying sleep and the many functions our brains perform during it. Learn more on #WorldSleepDay: scim.ag/4sFbutI

We also see a shift in CA1 recruitment during learning. Neurons active before the threat, when the animal is simply exploring the context, are excluded from the engram. This suggests that the hippocampus updates which neurons will store the memory as the experience unfolds.

How does the brain build a memory? A common assumption is that the neurons activated during an experience collectively form the memory engram. In our new Nature Neuroscience paper (finally out!), we show that this is not the case. nature.com/articles/s4159…

Back again for #OptoGRC2026—meet meeting co-chair @okaysteve! Steve is an associate professor at @BU_Tweets and is especially excited about mentor-mentee lunches and supporting the next generation of researchers. Fun fact: he calls his parents twice a day, every day 📞❤️

There’s still time to apply for #OptoGRC2026! 🙌 All applications are considered for support, including the opportunity for full registration coverage. Poster submissions & statements of interest encouraged! Apply by 2/20 to maximize your chances👇 grc.org/optogenetic-ap…

It's time to meet your #OptoGRC2026 chairs! Co-vice chair @tinakim_neuro is an assistant professor at @Princeton who spent the summer building a van for weekend adventures 🚐✨ She's most looking forward to meeting new people & exploring areas outside of her usual wheelhouse!

🚨 Reminder: Applications for #OptoGRC2026 are now OPEN! Don’t miss your chance to join an incredible week of science, discovery, and connection with the brightest minds in optogenetics 💡🧠 Apply now for the best chance of acceptance: grc.org/optogenetic-ap…

Introducing co-vice chair @InAnOther! Gisella is a team leader at @ESPCI_Paris and is most excited about the immersive exchange and new ideas #OptoGRC2026 will inspire. Fun fact: when she’s not studying neurons, you can find her spinning on a pole 💃💪

Meditations on memory | Science science.org/doi/10.1126/sc… It was an honour to review @okaysteve’s How to Change a Memory for Science. The book speaks for itself, bold, inspiring, and full of soul. I’m just proud to highlight the incredible work behind it. So proud of you, Steve

🚨 The paper from my postdoc in @GraeffJohannes 's lab at @EPFL is out! we show that memories can be switched on and off by simply changing the “packaging” of DNA in neurons through epigenetic editing. 🧬🧠🐭 nature.com/articles/s4158…

Steve Ramirez @okaysteve sat down with @FrankieRivera25 to discuss the inspiration behind the book, why he decided to write it partly as a memoir, and what he wants readers to take away from reading it. thetransmitter.org/memory/how-to-…

Excited to share the latest from the lab on the molecular mechanisms of silencing and un-silencing a hippocampal engram ensemble. (1/3) sciencedirect.com/science/articl…

In 2016, the first Opto GRC was created to bring together scientists pushing the boundaries of optogenetics research 🧠🌟 Join us to celebrate 10 incredible years of collaboration and discovery—applications for #OptoGRC2026 are now open! Apply now: grc.org/optogenetic-ap…
