This study identifies CeAIsl1+ neurons in the central amygdala that coordinate jaw and stomach functions during ingestion by modulating reflexes and gastric motility.

Serial transfer of low-activity mice gut microbiomes to germ-free mice reduced locomotor activity, showing microbiome transmission can influence host traits independently of genetic changes.

This study identifies a brain-gut circuit involving Brunner's glands that regulates intestinal microbiome composition and immunity.

The paper shows that gut microbes influence sympathetic neurons through a metabolite-mediated gut-brain circuit, with butyrate suppressing sympathetic activity.
