Multimodal Reorganization of Gut--Brain Physiology During the Cephalic Phase of Digestion
The vagus nerve plays a central role in gut--brain communication, yet the physiological dynamics associated with cholinergic vagal signaling remain difficult to characterize non-invasively in humans. The cephalic phase response, which prepares the gastrointestinal system for food ingestion through anticipatory vagal pathways, offers a unique opportunity to investigate these interactions. Here, we…
