A drop of milkshake takes a wild ride after it is swallowed. Rachel and Kiersten came up with cool strategies for visualizing food passing through the mouse GI tract and mapping the activity of the same 100s of brainstem neurons across weeks during feeding and other behaviors.
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. biorxiv.org/content/10.110…

2⃣A multitrait GWAS of adult obesity Combining genomic on BMI, waist and hip circumference, and waist-to-hip ratio from 2 million individuals, this multitrait GWAS identified 86 novel loci associated w/ obesity. 👉These loci could point to new potential targets for anti-obesity…
I read this Cell paper that argues to have discovered a molecule (betaine) that mimics the geroprotective effects of exercise. This is a very valuable multi-omics resource, but the authors seemed to get caught in the rabbit hole of chasing a high-impact narrative🧵

Our #brain has a sweet tooth 🧠🍫 Nerve cells that tell to us we are full also make us crave #sweets ! mpg.de/24159607/0211-… @MPI_Metabolism
Our new paper is out in @CellReports We show an inhibitory response of Orexin receptor type 2 (Ox2R) in a subset of MCH neurons. doi.org/10.1016/j.celr…
What's the key to a fast marathon? A lot of "slow" miles. According to a new study analyzing 151,813 marathon performances, how runners distribute their training intensity is a key predictor of race-day performance. The study examined training logs from runners of all levels,…
Two papers in Nature present the origins of the Yamna (also known as Yamnaya), the pastoralists who migrated from the Eurasian steppe into Europe 5,000 years ago. go.nature.com/40MR4Cx go.nature.com/411BUKV
I am excited to share our latest paper @Nature where we construct a hi-res spatial map of the human hypothalamus, the brain region central in appetite control. It is a collaboration between @IMS_MRL @Cambridge_Uni & @MPI_Metabolism nature.com/articles/s4158…
Modulation of Neural Circuits and Behavior GRC is nearly 100 days away! Check out the amazing list of speakers and join us for a scintillating series of talks!
Congrats to @pnkalugin! Right at the start of my postdoc I had a great opportunity to join the team and image in vivo the dynamics of hormone sensing and bio-distribution at the choroid plexus in the lateral ventricles! Glad to see it out! 🧠🎉 #hormonesensing #opticalsensors
I’m thrilled to share our preprint presenting MORSE: a new way to simultaneously and quantitatively track patterns of neuromodulators/neuropeptides in vitro & in vivo using spatially multiplexed 3D imaging of 10+ green optical sensors on a microendoscope. biorxiv.org/content/10.110…
