Bioengineered sensors have helped reveal the activity of neuropeptides in the brain, researchers reported in 2023 in Science, providing novel tools for studying the release, function, and regulation of these crucial signaling molecules in vivo. Learn more in this

📢 Excited to share our new paper out today in Nature Neuroscience! 🧠✨ We uncover how compartmentalized dendritic plasticity in the retrosplenial cortex (RSC) links contextual memories formed close in time. A thread 🧵👇 [1/8] nature.com/articles/s4159…

Our recent paper was featured in an article in PsyPost.org: psypost.org/brain-inflamma… Kiruthika Ganesan

🚨📃New Wassum Lab Paper📃🚨 Jackie Gio discovered brain pathways that support agency and habit and how chronic stress disrupts them to rob of us our agency and cause us to form rigid habits 🧵👇 nature.com/articles/s41... Free full text: rdcu.be/eaxEv

Forever grateful for the opportunity to have you as my mentor. The best mentor I could ever ask for as a grad student! You are an absolute legend. Thank you for everything.

If you eat something and get sick, you shouldn't eat that thing again. Problem is, there is a long delay between when you eat and when you feel sick -- how can the brain link the two events? This cool paper shows us how the process works nature.com/articles/s4158…

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…
