Is there a single "interoceptive sense"? Our new study in @commspsychol.nature.com says: probably not. In 241 participants, cardiac and respiratory interoception were completely uncorrelated — only subjective confidence was shared across domains. www.nature.com/articles/s44... #psychscisky 🧪
  Graphical abstract showing three panels. Left panel, "Multiorgan Interoception Measures," depicts a translucent human body
   silhouette with anatomically rendered heart (red) and lungs (blue), accompanied by schematic icons for three
  psychophysical tasks: the Respiratory Resistance Sensitivity Task (RRST), Heart Rate Discrimination Task (HRDT), and an
  auditory control condition. N = 241 participants. Center panel, "Psychophysical Modelling and Individual Differences,"
  shows a fan of overlapping sigmoid psychometric curves in blue-to-red gradient representing individual variation in
  perceptual threshold (α) and precision (β), a hierarchical Bayesian model diagram, and icons for metacognitive bias and
  M-Ratio efficiency. Right panel, "Key Finding: No Cross-Modal Relationship," displays a scatterplot of cardiac versus
  respiratory sensitivity with a flat regression line (r ≈ 0, BF₀₁ > 6), a compact Bayes Factor heatmap with mostly blue
  null-supporting cells and one orange cell indicating that subjective confidence is shared across modalities (r = 0.51***).
   Takeaway: interoceptive ability is modality-specific.

Are you curious about electrogastrography, but keep getting chicken-related results when googling "EGG"? We have the preprint for you! In this tutorial, we describe how to acquire and analyse gastric data from human participants. Plus FREE software! Read it here: arxiv.org/abs/2509.17260
Image illustrating sensor placement. The reference sensor is placed on the xiphoid process (just under the sternum), the ground is placed on the left costal margin (just under the bottom rib), and sensors one through four are place over where the stomach would be. Sensor 3 is midway through the umbilicus (navel) and the reference sensor. Sensor 4 is roughly three centimetres from sensor 3 to participant-right. Sensors 2 is also roughly three centimetres away from sensor 3, but along a 45 degree angle upwards and to participant-left. Sensor 1 lies 3 centimetres further from sensor 2, along the same 45 degree line.Two-panel image showing a processed electrogastrogram. The left panel shows five minutes of raw data from four different leads (measured from the four sensors in the previous image and their common reference). The right panel shows the same signal in frequency space, illustrating the typical normogastric peak at 3 cycles per minute.

Can we enhance interoception by controlling the heart? Thrilled to share our new study, led by @ashleytyrer.bsky.social , where we use computational modeling to show that blockading peripheral noradrenaline uniquely alters awareness of heart rate & breathing! www.biorxiv.org/content/10.1... 🧵👇
A graphical abstract titled "Can Beta-Blockers Manipulate Interoception? A Placebo-Controlled Study." The image illustrates how bisoprolol and propranolol affect interoception. On the left, a green figure represents bisoprolol, showing a zoomed-in synapse where it selectively blocks β1 receptors. On the right, a purple figure represents propranolol, blocking both β1 and β2 receptors, affecting both brain and body. A psychophysics graph models interoceptive responses, showing response intensity over trials. Below, line plots compare placebo, propranolol, and bisoprolol effects on interoception—cardioception (threshold) and respiroception (slope)—indicating drug effects on bodily awareness.
