Central sensory-motor crosstalk in the neural gut-brain axis

The neural gut-brain axis consists of viscerosensory and autonomic motor neurons innervating the gastrointestinal (GI) tract. Sensory neurons transmit nutrient-related and non-nutrient-related information to the brain, while motor neurons regulate GI motility and secretion. Previous research provides an incomplete picture of the brain nuclei that are directly connected with the neural gut-brain axis, and no studies have thoroughly assessed sensory-motor overlap in those nuclei. Our goal in this study was to comprehensively characterize the central sensory and motor circuitry associated with the neural gut-brain axis linked to a segment of the small intestine.
