Understanding how the brain and gut communicate without invasive procedures
Non-invasive assessment and modulation of brain-gut interoception in humans
This study is looking at how your brain and gut communicate with each other and how that affects your digestion, using safe techniques like MRI scans while you eat, to help us learn more about gut health.

What this research studies
This research investigates how the brain and gut interact through a process called interoception, which involves sensing and interpreting internal bodily signals. Using non-invasive techniques, including MRI and a method called transcutaneous auricular vagal nerve stimulation (taVNS), the study aims to explore how these interactions affect gastric function and brain responses. Participants will undergo MRI scans while ingesting calibrated meals to assess how their bodies respond to these signals. The goal is to enhance our understanding of the gut-brain axis and its implications for gastrointestinal health.
Who could benefit from this research
Good fit: Ideal candidates for this research are adults over 21 years old who may experience gastrointestinal disorders or are interested in understanding their gut-brain interactions.
Not a fit: Patients with severe neurological conditions or those unable to undergo MRI procedures may not benefit from this research.
Why it matters
Potential benefit: If successful, this research could lead to new non-invasive treatments for gastrointestinal disorders by improving our understanding of brain-gut communication.
How similar studies have performed: While the approach of using taVNS and MRI to study the gut-brain axis is innovative, similar non-invasive techniques have shown promise in related fields, suggesting potential for success.
