"The interoceptive origin of reinforcement learning" http://dlvr.it/TPHbz0 Frederike H. Petzschner, @danasmall.bsky.social & colleagues @cp-trendscognsci.bsky.social #SfN2025
Is overeating driven by hedonism? @danasmall.bsky.social &co argue that the pleasure of eating food is not a driver of the #obesity epidemic, but rather the regular consumption of an unhealthy diet blunts sensitivity to interoceptive signals that drive food reward #neurosky 🧪 plos.io/4nTlHQc
Amid lots of uncertainty, anger, and exhaustion I am excited to share this work from my incredibly talented MSTP and @nuincomm.bsky.social student Haley Province. In it we explore the fascinating and powerful anti-aversive properties of GIPR agonists

I think Mark is onto something with this one. Totally agree that there is something wrong with onions. open.substack.com/pub/markscha...
Something is Wrong with Onions
They are getting less irritating and less pungent, which means they’re losing flavour. That isn’t good.

A drop of milkshake takes a wild ride as it passes through the body. Rachel and Kiersten and the team 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.
Rachel Essner@rachelessner.bsky.social · last yr.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. www.biorxiv.org/content/10.1...
