Very exciting to see our work being highlighted by @thetransmitter.bsky.social! Thanks to Natalia Mesa, and as always thanks to our collaborators in the Jayaraman lab!… back to grinding away at reviewer experiments

My final paper from grad school is out! Thank you to @marisosa.bsky.social @ellasay.bsky.social and my co-first author Konstantin Kaganovsky! We show that reward and novelty coding in the hippocampus requires a specific membrane fusion protein implicated in activity-dependent AMPAR mobilization!

I am incredibly excited and proud to share my first preprint from my postdoc! Thank you to all of the co-authors for all your hard work! Check out the paper for big insights into plasticity mechanisms in navigation circuits! And surprising motifs for inhibitory synaptic plasticity!

It's officially published!! In my main postdoc work with @markplitt.bsky.social and @lgiocomo.bsky.social, we found that the hippocampus simultaneously encodes an animal's spatial position and its experience relative to reward in parallel population codes. 🧵 www.nature.com/articles/s41...

Sosa et al. find that hippocampal neural activity in mice encodes both environmental location and experience relative to rewards, spanning distances far from reward, through parallel and flexible popu...
