Disruption of visual cortical activity and offline reactivations of recent salient experience in the hours following training on a task associating cues with outcomes completely blocks across-day learning!

Exciting work by Kristian, Marianne and their team!

We previously showed that specific hypothalamic neurons get more and more activated by each bite of food until they put a brake on homeostatic feeding. Here, we find that this brake is already on at the start of a meal in obese mice on a high-fat diet.

Congrats to Marta, Stephen and the whole team!

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.
