” We were able to localize many of the capsule stimulations to the gastroduodenal segments of the digestive tract using stomach X-ray imaging,” said Dr. Sahib Khalsa, a psychiatrist and neuroscientist at LIBR, and senior author of the study. “This finding is vital as it supplies a more precise understanding of where these gut-brain interactions are originating.”
” The prospective scientific ramifications for the results of this study are significant,” said Dr. Khalsa. “The vibrating pill approach might transform the scientific method to conditions of gut-brain interaction, including consuming conditions and particular gastrointestinal conditions such as irritable bowel syndrome (IBS) or practical dyspepsia.”
Dr. Khalsa continued. “This would supply a much-needed tool for assessing gut experience in these conditions and could lead to more effective and personalized treatment methods. It also opens the possibility of determining affective or biological conciliators of effective treatment, which could act as predictive markers for future therapeutic interventions.”

The research team was led by senior author Sahib Khalsa, MD, PhD, Director of Clinical Operations at the Laureate Institute for Brain Research and Associate Professor in the Oxley College of Health Sciences at The University of Tulsa. Co-first authors on the research study were Ahmad Mayeli, PhD and Obada Al Zoubi, PhD who were a PhD trainee and postdoctoral scholar, respectively, from LIBR at the start of the project.
The research study was supported by the National Institute of Mental Health and The William K. Warren Foundation and was carried out at LIBR between September 2019 and February 2022.
Researchers at the Laureate Institute for Brain Research have made advancements in comprehending the gut-brain connection utilizing an unique vibrating pill for gastrointestinal stimulation. The study, released in Nature Communications, recommends the potential for a revolutionized approach to gut-brain conditions, including individualized treatments and predictive markers for interventions.
A pioneering study conducted by scientists at the Laureate Institute for Brain Research (LIBR) in Tulsa, Oklahoma, has made considerable strides in understanding the elusive gut-brain connection, a complex relationship that has long puzzled scientists due to the trouble of accessing the bodys interior. The study, “Parieto-occipital ERP indicators of gut mechanosensation in people,” will be published today (June 13) in the peer-reviewed clinical journal Nature Communications.
The research team successfully had individuals swallow a minimally intrusive vibrating pill to determine neural actions throughout gastrointestinal stimulation, offering an unique technique to study this elaborate connection. The capsule was developed by Vibrant Ltd. Participants in the research study included healthy adult male and female volunteers ages 18-40. The scientists discovered that the volunteers had the ability to notice the stimulation of the vibrating capsule under two conditions: regular and enhanced. The improved stimulation condition led to enhanced affective precision, much faster detection of the stimulation, and decreased irregularity in response time, suggesting potential for studying this technique in different clinical populations. This is a substantial advancement as it shows the feasibility of this novel method to studying gut feelings.
The scientists also found the “gastric evoked potential,” a late neural response in specific locations of the brain particularly caused by pill stimulation. These neural actions increased in amplitude depending upon the intensity of the stimulation and were significantly correlated with affective precision. This discovery provides a new method to measure and understand the neural processes governing the gut-brain connection.
