Accordingly, stimulating these sensory neurons is rewarding and sufficient to condition taste or place preferences.</p><p>Although now pivotal in neurogastroenterology, this work was initially met with conceptual and technical obstacles. For example, the vagus nerve was typically associated with negative valence, acting as a brake to cease feeding and promote satiety. However, using trans-synaptic viral tracing, this study demonstrated that gut-innervating vagal afferent nerves directly ascend to and activate reward-processing brain regions.

These priorities emphasize quantifying the burden of IBD, addressing health-care disparities, validating care models, exploring novel treatments, advancing education, engaging patients and advocating for health equity policies.
