6/ Thank you also to @haganK and @Oren_Amsalem for their analysis wizardry, Sverre & Kristian for sharing the ribo-GCaMP, and Teresa for her fluoroscopy expertise. I am also beyond grateful for @andermann_mark for all of his guidance, support, and excitement throughout the years.

5/ Huge thanks to @RudamntaryNeuro and @hannahchoh (Team PBN!) – this project was a ton of work and could not have been done without them.

4/ Other spatially clustered LPBN neurons were sensitive to arousal and body movement. Together, our results define functional specialization in LPBN and highlight a platform for studying interoception during behavior. Check out the full manuscript for many other cool findings!.

3/ Indeed, by imaging the same neurons across days, we found that Late Ensure neurons are sensitive to stomach stretch, malaise, and satiety signals. These Early vs. Late Ensure neurons were also spatially organized within LPBN.

2/ We coined neurons that became active at the onset of consumption as “Early Ensure neurons” and those that became active 1-3 s later as “Late Ensure neurons.” We suggest that Early neurons are sensitive to oral signals, while Late neurons are sensitive to post-ingestive signals.

1/ Food (Ensure) consumption drove a seconds-long wave of activity across LPBN, with dynamics that mirrored movement of food through the upper GI tract observed using X-ray fluoroscopy.

I’m so excited to share our preprint on how brainstem neurons sense and integrate multiple body signals during food consumption. We imaged 1000s of neurons across the lateral parabrachial nucleus (LPBN) in behaving mice.

Williams is the best! Could not recommend it more :).
The Williams College Biology Department is hiring a tenure track Neurobiologist! This is the perfect faculty position for anyone who wants to pursue research and teaching in an inclusive and supportive community. Feel free to DM me with any questions! .

This is an awesome guide to techniques in neuroscience (in my unbiased opinion). Check it out! 👇🏻.
Happy to announce the release of a new, 3rd Ed. of Guide to Research Techniques in Neuroscience. A handy guide to learn about common and cutting-edge methods. With new co-authors… @NitsanGoldstein @RachelEssner and Manasi Iyer.
