Parallel gut-to-brain pathways orchestrate feeding behaviors.

The caudal nucleus of the solitary tract (cNTS) in the brainstem serves as a hub for integrating interoceptive cues from diverse sensory pathways. However, the mechanisms by which cNTS neurons transform these signals into behaviors remain debated. We analyzed 18 cNTS-Cre mouse lines and cataloged the dynamics of nine cNTS cell types during feeding.
