”Got Guts” The Micro Version: Characterization of Rat Gastric Slow Wave Activity

Tune in to our latest podcast episode where Peng Du, Omkar N. Athavale, and Madeleine R. Di Natale dive into the fascinating world of gastric slow-wave conduction. They discuss their recent article titled "Mapping the rat gastric slow-wave conduction pathway: bridging in vitro and in vivo methods, revealing a loosely coupled region in the distal stomach" revealing regional variations in the organization of rat gastric slow waves. Don't miss this intriguing discussion bridging in vitro and in vivo methods!

 

Mapping of rat gastric slow waves showed regional variations in their organization. In some subjects, separate wavefronts propagated near the lesser and greater curvatures with a loosely coupled region near the midline, between the wavefronts, having a varying slow-wave origin. Furthermore, simultaneous intracellular and extracellular recordings were concordant and independent of movement artifacts, indicating that extracellular recordings can be interpreted in terms of their intracellular counterparts when intracellular recording is not possible.
