If you are a student and postdoc interested in body-brain communication - check out Chris's lab!

I’m very excited to share that I will join the University of Utah Department of Neurobiology as an Assistant Professor in Jan 2026!! 🎉🏔️🏜️

My lab will focus on body–brain interactions in learning & memory — how do signals from our internal organs remodel the brain & behavior?

Unbelievably proud of @nataliefigueredob.bsky.social for winning the prestigious Bogue Fellowship 🌟 She'll be heading across the pond to train with the @zknight.bsky.social lab for 3 months. Exciting things to come for this bright young scientist 🧠. @uclnpp.bsky.social @ccmnlondon.bsky.social

We've had advances in green genetically encoded Ca2+ indicators (GECIs), but what about red-shifted GECIs? @piatkevich.bsky.social &co present SomaFRCaMPi, a new soma-localized red #GECI that exhibits improved accuracy & sensitivity for in vivo neuronal imaging @plosbiology.org 🧪 plos.io/3YnCqRW
Top left: Representative single plane confocal images showing fore-, mid-, and hindbrain regions of live zebrafish larva expressing jRGECO1a, FRCaMPi, and SomaFRCaMPi in neurons driven by the HuC promoter (n = 10 fish at 6 dpf for each). Bottom left: Schematics of looming stimulation set up in which black expanding circular shadows projected in front of the larval zebrafish embedded in agarose gel. Right: Representative single trial fluorescence traces of soma and neuropil region of red GECI-expressing neurons during looming stimulation shown as ticks.

🚨📃New Wassum Lab Paper📃🚨

Out today, @jackiegio.bsky.social 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 🧵👇

A dual-pathway architecture for stress to disrupt agency and promote habit - Nature
Adaptive decision-making often requires an understanding of our agency in a situation; however, chronic stress can disrupt agency and promote inflexible, habitual behaviour by turning off a brain path...

Chris is an incredible talent who transformed our understanding of thirst when he was a student in my lab. Wonderful to see the progression of his science and thrilled that he's on the job market!

Impressive new study from Chris Zimmerman shows that visceral malaise reactivates the representation of recently consumed flavors, providing a mechanism for post-ingestive learning.
