I recently discussed AI use for medical theses with military medicine residents. My answer to “Should we use it?” was yes—with four guiding principles: verify claims, protect data, disclose AI use, and take responsibility for the final work. (4/4)

These findings identify gastrointestinal #interoception as a potential prognostic biomarker in AN and point to brain-body interactions as a key target for future precision #psychiatry. (5/6)

Charles Verdonk @ch-verdonk.bsky.social · 17/06/2026

Key findings: ⚡ Individuals with AN showed reduced detection of gut signals despite preserved neural and physiological responses. ✅ Gastric stimulation increased hunger in AN. ✅ Altered gut perception predicted relapse risk and symptom severity 6 months after discharge. (4/6)

Charles Verdonk @ch-verdonk.bsky.social · 17/06/2026

In this work, we tested whether gastrointestinal interoception - the brain’s ability to sense gut signals - could reveal hidden vulnerabilities. Using an ingestible vibrating capsule, we combined behavior, EEG, and physiology to probe gut signal detection. (3/6)

Charles Verdonk @ch-verdonk.bsky.social · 17/06/2026

Relapse remains a major challenge in anorexia nervosa (AN) - even after apparent recovery – and clinicians still lack objective markers to monitor recovery and predict relapse. (2/6)

These findings establish IAF not only as a stable individual trait, but also as a trainable neural property that shapes the temporal dynamics of attention. 6/7

120

Charles Verdonk @ch-verdonk.bsky.social · 12/04/2026

Notably: Mediation analyses revealed a causal chain—neurofeedback increased IAF, which sped up α-ERD dynamics, ultimately leading to faster behavioral responses. 5/7

Charles Verdonk @ch-verdonk.bsky.social · 12/04/2026

𝐊𝐞𝐲 𝐟𝐢𝐧𝐝𝐢𝐧𝐠𝐬: ✅ Participants who successfully increased their IAF (“learners”) showed faster reaction times and greater response efficiency on the Attention Network Test. ⚡ They also exhibited shorter α-ERD latencies, reflecting faster allocation of cognitive resources. 4/7

Charles Verdonk @ch-verdonk.bsky.social · 12/04/2026

In a double-blind, sham-controlled EEG #neurofeedback study, we tested whether increasing IAF could enhance attentional performance by shaping the temporal processing of visual information. 3/7

Charles Verdonk @ch-verdonk.bsky.social · 12/04/2026

Attention depends on the brain’s ability to flexibly align its internal rhythms with the world around us. Yet the role of these rhythms - especially IAF - in attentional processes remains poorly understood. 2/7

Our sample was #military personnel, but the findings may inform prevention in elite #sport and other heat-exposed settings. Assessing interoception could help identify vulnerable individuals and guide return-to-duty and other prevention strategies 5/6

We tested the model with self-report measures in people with vs. without prior EHS. Cases (n=51) reported lower interoceptive body awareness but no difference in global motivational traits versus controls (n=43) 4/6

100

Charles Verdonk @ch-verdonk.bsky.social · 19/10/2025

We propose a cognitive model in which EHS arises from a disturbed cost–benefit trade-off during prolonged exertion: excessive motivation overvalues performance benefits, while low interoceptive awareness undervalues bodily costs (see figure) 3/6

100

Charles Verdonk @ch-verdonk.bsky.social · 19/10/2025

EHS is classically described as a purely physiological failure - heat gain exceeds heat loss (see figure) - but physiological models alone cannot fully explain or predict who develops EHS 2/6
