Scientists discover surprising link between gut-brain interactions and mental health | Eric W. Dolan, PsyPost A new study provides evidence that the connection between the brain and the stomach may be linked to mental health in a measurable way. Researchers from Aarhus University in Denmark, publishing their work in Nature Mental Health, report that a specific pattern of communication between the brain and the stomach reflects how individuals feel emotionally and psychologically. Their findings suggest that these gut-brain interactions can indicate a person’s levels of anxiety, depression, well-being, and overall quality of life. The idea that emotions are linked to physical sensations in the gut is widely reflected in language. People often talk about having “butterflies in the stomach” when nervous, or feeling “sick to the stomach” when distressed. Yet, despite these common expressions, most scientific attention in the field of brain-body interaction has focused on other organs, such as the heart and lungs. These areas have long been studied for their roles in emotion and mood. The researchers were struck by how little was known about how the stomach, in particular, interacts with the brain. While recent studies have explored the influence of gut bacteria and digestion on mental health, very little work had been done on the electrical rhythms of the stomach and how they may directly communicate with the brain’s networks involved in emotion, attention, and cognition. The team behind this new study wanted to explore whether a person’s psychological profile might be reflected in how strongly the stomach and brain are coupled during rest. Their aim was not to link a specific diagnosis like depression to a single brain region, but rather to identify patterns across a broad spectrum of mental health experiences. “Our interest grew from the long-standing discussion about the role of the body in shaping emotion, a question that has fascinated philosophers and scientists for centuries,” said study author Leah Banellis (Leah Banellis), a postdoctoral fellow in Cognitive Neuroscience at Aarhus University. “Yet, while the heart and lungs have received much attention, the stomach has been largely overlooked. This gap struck us as especially surprising, because the link between the stomach and emotional experience feels so intuitive. It is heavily reflected in everyday language, with phrases like ‘butterflies in the stomach,’ ‘sick to our stomach,’ or ‘trust your gut.'” The research was part of the Visceral Mind Project, a large-scale initiative that combines data on brain activity, bodily rhythms, and psychological assessments. The team recorded data from 243 people using a method that captures both electrical signals from the stomach (electrogastrography) and brain activity measured with functional magnetic resonance imaging (fMRI). The participants represented a wide range of mental health profiles, from those reporting high well-being to others showing signs of distress, including anxiety, depression, fatigue, and insomnia. To capture this diversity, the researchers didn’t exclude people with psychiatric symptoms or diagnoses. Instead, they aimed for variation, which would allow their models to detect patterns across the mental health spectrum. Each participant underwent a series of recordings while lying still in the MRI scanner. At the same time, sensors on the abdomen captured the stomach’s slow electrical rhythm, which cycles about three times per minute. This rhythm, which originates from specialized cells in the stomach lining, is typically involved in coordinating digestion. But the researchers suspected it might also be linked to mental state. To analyze the relationship between stomach and brain activity, the team used a method that looks at how well the two rhythms align over time. This measure, known as phase-locking value, essentially captures the degree of synchronization between stomach signals and brain signals across different regions. The researchers then combined this data with results from a comprehensive mental health questionnaire. The battery included 37 different scores across a range of domains—such as anxiety, stress, mood, fatigue, attention, sleep quality, and life satisfaction. Using a statistical method known as canonical correlation analysis, they looked for patterns that linked brain-stomach coupling with the participants’ mental health profiles. The analysis revealed a clear and statistically significant pattern. Stronger coupling between the stomach’s rhythm and brain activity was associated with poorer mental health. Individuals who reported more symptoms of anxiety, depression, stress, and fatigue tended to show increased synchronization between their stomach and brain rhythms. In contrast, those with higher levels of well-being and life satisfaction showed weaker coupling. “For the first time, we’ve found a scientific link between your ‘gut feelings’ and your mental health, showing a surprising connection between your stomach’s natural rhythm and your brain,” Banellis told PsyPost. “Specifically, our study revealed that stronger communication between the stomach and brain is linked to worse mental health, such as higher symptoms of anxiety, depression, stress, and fatigue, whereas weaker stomach-brain communication aligns with better mental health reflected in higher overall well-being and quality of life.” This stomach-brain signature was not random. It was localized in specific brain networks, particularly those involved in attention, cognitive control, and salience detection. Some of the strongest associations were found in regions like the superior angular gyrus and the posterior frontal and parietal areas—regions often implicated in cognitive tasks and mental health disorders. Importantly, the researchers ran multiple control analyses to ensure the robustness of their findings. They ruled out the possibility that the observed effects were simply due to general brain activity patterns, fluctuations in heart rate or breathing, or basic features of stomach physiology. In other words, the association appeared specific to the coupling between the stomach’s electrical rhythm and particular brain networks—not just a general marker of body or brain state. Their approach was designed to detect broad psychological dimensions rather than focus on one diagnosis. The strongest psychological pattern they found was a spectrum ranging from negative affective states (like anxiety and depression) to positive traits (like well-being and quality of life). This result suggests that the stomach-brain connection is not tied to any one disorder but instead reflects a general mode of psychological functioning. “Anxiety, depression, stress, and fatigue showed the strongest links to stomach-brain communication,” Banellis explained. “While phrases like ‘butterflies in the stomach’ or feeling ‘sick to your stomach’ are common ways we describe emotional distress, it was surprising to find such consistent and clear evidence across these symptoms. Even more unexpected was the direction of the effect: we might have assumed that stronger alignment between the body and brain would be beneficial. Instead, our findings suggest that heightened stomach-brain communication could act more like a warning signal, an internal alarm system reflecting mental strain rather than harmony.” Read more:

Psychologist Jonathan Haidt on why he says social contagion is behind the surge in the number of cases of people claiming to be transgender: "Because it happens in clusters of girls, it happens in clusters of girls who had no previous gender dysphoria when they were young." HAIDT: So there’s very important, older research by Nicholas Christakis and, James Fowler where they looked at, they had gigantic health data sets, the Framingham Heart Study, and they were able to see that, you know, if one person takes up smoking, their friends are more likely to take up smoking, but actually, so are their friends friends and even friends, friends, friends. So the things we do spread out through social network. We affect each other. Now it turns out, when you’re looking at emotions, girls and women, when they study women, when a woman is depressed, that spreads out to her network. Whereas when a man is depressed, it doesn’t. Women talk about their feelings. They’re more connected in that way. Girls are connecting on social media, where it just turns out in many communities, the more anxious and depressed you are, the more you get support. The more extreme your symptoms, the more you get likes and followers. You know, of course it’s good to destigmatize social, mental illness. We don’t want people to be ashamed. But boy, is it a terrible idea to valorize it, to tell young people, ‘You know what? The more you have this, the more popular you’ll be, the more support you’ll get.’ And so you get this explosion, not just of anxiety – anxiety is in part, I think, spread sociogenically, it’s called, from social causes, not from internal causes – but we get it for dissociative identity disorder. And it seems to be the case for gender dysphoria as well. HOOVER: And you think that the data demonstrates that it is above and beyond just the phenomenon of coming out and increased awareness? HAIDT: Yes. Because it happens in clusters of girls. It happens in clusters of girls who had no previous gender dysphoria when they were young. So it’s very different from the kinds of gender dysphoria cases that we’ve known about for decades. I mean, it is a real thing. But what happened, especially when girls got, was YouTube and Instagram early, but then especially TikTok, girls just, you know, girls get sucked into these vortices and they take on each other’s purported mental illnesses.

🚨Oxford Research Team Wraps Up New Study and Concludes: STOP universal mental-health interventions in schools - it makes too many kids worse One of the original Oxford researchers of the 2023 study announces they have published this week an updated study concluding universal school-based interventions based on CBT and mindfulness theories have significant probability of resulting in negative effects, warranting their discontinuance in universal settings. Full text: "Can mental health lessons in schools sometimes make young people feel worse? Well, this is a question that we asked in a review paper that we published this week. And we looked specifically at lessons that taught either CBT [cognitive behavioral therapy] or Mindfulness to groups of young people in schools What we found was that in 9% of these studies something that was supposed to improve like depressed mood or peer relationships ended up getting worse and not better. And when we look specifically at the high quality studies, so the ones with big sample sizes and good statistics that we can really trust, that figure increased to 33%. So, in a third of these studies, something that was supposed to improve ended up getting worse in the group of young people who had these either CBT or mindfulness lessons. Importantly, this only happened in universal interventions, so that's when this mental health information is taught to the whole class, regardless of need. I think this evidence, combined with other evidence that we have, suggests that we should start moving away from this universal approach to mental health in schools where everyone is taught about mental health and move towards more effective approaches like one-to-one support or small group support for people who either want or need it. There's much more information about all of this in the paper, which I will link to."

Jordan Peterson on why social anxiety is really a self-focus problem: Dr Jordan B Peterson explains that social anxiety is fundamentally driven by excessive self-referential thinking. "If you're feeling social anxiety in a situation, part of the reason for that is because you're thinking about how you're feeling." He points to fascinating research on language patterns and mental health. When you analyze the words people use in speech and writing, a striking pattern emerges: the more someone refers to themselves, the more likely they are to be depressed or psychotic. "You can actually distinguish with 75% accuracy between people who are clinically depressed or clinically psychotic and people who aren't by the number of times they refer to themselves." The core insight is simple but powerful: "The more you think about yourself, the more miserable you are." But Peterson warns against the obvious trap in trying to fix this. You can't just tell yourself to stop thinking about yourself. That's still thinking about yourself, and you'll fall into the same pit. Instead, he offers a practical redirect: "If what you decide to do is to pay way more attention to the other person and try to make them comfortable, then that social anxiety will disappear." The solution is a redirection. Rather than fighting your own self-consciousness, you shift your entire attention outward. Make the people around you more comfortable. Focus on them, not on how you're coming across. It's a counterintuitive reframe: the cure for feeling awkward is caring less about your own performance and more about the person in front of you.
