Stomach serosal arteries distinguish gastric regions of the rat Open
Because the stomach in situ has few distinctive surface features and changes shape dramatically with food intake, we have used micro‐CT imaging combined with two distinct contrast agents to (1) characterize the pattern of arteries, potenti…

Stomach serosal arteries distinguish gastric regions of the rat Open
Because the stomach in situ has few distinctive surface features and changes shape dramatically with food intake, we have used microCT imaging to (1) characterize the pattern of arteries, potential landmarks, on the stomach wall and (2) ev…

Stomach region stimulated determines effects on duodenal motility in rats Open
Gastric electrical stimulation (GES) is used clinically to promote proximal GI emptying and motility. In acute experiments, we measured duodenal motor responses elicited by GES applied at 141 randomly chosen electrode sites on the stomach …

Micro-CT imaging of rat stomach vasculature v1 Open
This protocol describes how to prepare a rat stomach for micro-CT imaging of the vasculature. A lead-containing silicone-based curable material is injected into the heart at perfusion and flows through the vasculature and cures in place. S…

Micro-CT imaging of iodine-stained rat stomach v1 Open
This protocol describes how to prepare a rat stomach for micro-CT imaging to enable a 3D description of the organ. Iodine is used to stain the tissue post-perfusion. By varying the meal size and the delay time between feeding and perfusion…

Vagal innervation of the stomach reassessed: brain−gut connectome uses smart terminals Open
Brain−gut neural communications have long been considered limited because of conspicuous numerical mismatches. The vagus, the parasympathetic nerve connecting brain and gut, contains thousands of axons, whereas the gastrointestinal (GI) tr…
