Out now in @natcomms.nature.com, our latest from @bodybrainbehaviour.bsky.social: Visual perception, oscillatory excitability markers, and network connectivity are modulated by the breathing rhythm - depending on how much you know about the stimulus.

New paper in Imaging Neuroscience by Zhishun Wang, Jack Grinband, et al:
MEPrep: A robust pipeline for multi-echo fMRI denoising and preprocessing
doi.org/10.1162/IMAG...
More importantly, do you use a fixed % rule, mean FD, or minimum clean duration remaining?
rs-fMRI methods question for the hive mind:
What’s your practical cutoff for excluding a whole resting-state run due to motion? Using FD > 0.3 mm as the threshold, at what % of contaminated frames do you usually drop the run?
🧵 I gave Claude two things: a short paper (doi.org/10.1073/pnas...) and a raw behavioural dataset with 3 lines of variable descriptions.
Then I asked it to fit three computational RL models described only by equations in the manuscript. No code, no toolbox, no guidance on the fitting procedure. 1/3
matlab is fun until you have to start paying for your lab’s licenses
Congratulations Leah what an unstoppable force!!!
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.
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 🧪
Incredibly excited to finally share this project! Most heartfelt thanks to everyone involved for their support 🫶🏻 Looking forward to much more gut-brain research to come!
So thrilled to see this work out. the stomach rhythm modulates brain wide electro physiological rhythms in resting wakefulness. It’s been a real privilege to collaborate with brilliant @teresaberther.bsky.social and @danlikesbrains.bsky.social in this project. hopefully first of many
New @bodybrainbehaviour.bsky.social preprint, and this is a big one for the lab: @teresaberther.bsky.social did the deepest of dives into #gut-brain coupling with MEG and HD gastrography.

A brief 🧵on our first trip into this corner of #brain-body #neuroskyence:
"...interoceptomimetics that stimulate gut–brain communication may counteract age-associated cognitive decline"
In mice but still 😊
@brainandstomach.bsky.social
My word of the day: "interoceptomimetics"

Happy to share our new Opinion now out in @cp-trendsneuro.bsky.social, with Catherine Tallon-Baudry and Anthony Clément!

#MSCA success rates now below 10%, yet the work that goes into writing this application is immense. Beyond the obvious increase in funding we need to find ways to lighten the time investment as well. Thousands of researchers spend weeks if not months working on this.
And I was complaining of Berlin’s —7
congrats Diego!!! See you in Rome
New preprint with Nicolai Wolpert and Catherine Tallon-Baudry !
Reaction times across three distinct perceptual tasks (total N = 90) varied with the electrical rhythm of the stomach.

Over the years, I have written a few Jupyter/Rmd/Matlab notebooks that attempt to teach some statistical concepts, particularly in neuroimaging. You can find them here: www.mrc-cbu.cam.ac.uk/people/rik.h..., though I will say a bit more about each one in a number of posts over next few days.
these books were really useful during my PhD. What about yours?
- Analyzing Neural Time Series Data
- Practical MATLAB for Brain and Cognitive Scientists
- Handbook of Psychophysiology
- The Integrative Action of the Autonomic Nervous System
- Handbook of Electrogastrography
I'm starting to build the lab's library, and would love hear your #1 essential book recommendation in Autonomic Neuroscience / Interoception, stats for Neuro/Psy science and any other must-have lab bible
Is a good bias!!
did it double over the last few years?
Hive mind: what resources would you recommend for students with little or no coding experience who want to learn MATLAB for cognitive neuroscience? I'm thinking (free) online courses or books
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.
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

So happy this paper is now out in @plosbiology.org! We investigated whether fluctuations in MEPs can be explained by phasic influences from internal bodily rhythms, and whether this might happen independently per organ system.

Thank you @dalmaijer.bsky.social for this excellent spotlight on our stomach-brain synchrony research! The analysis beautifully highlights how "more interoception isn't always better", it's about the context and interpretation of bodily signals.
Preprint -
Excited to present WHOLISTIC, which extends the concept of whole-brain functional imaging to the entire body. Pioneering work by incredibly talented Virginia Ruetten @vmsruetten.bsky.social, this platform reveals whole-organism cellular dynamics in vivo.
