Brilliant!👏 Cold (non-painful) or heat (painful) stimulation was rated as significantly more intense when participants expected it to occur with a substantial delay vs. a small or no delay. Ratings didn't correlate with actual delay. Prediction errors correlated with EEG activity but not ratings.

The spinal neurons can enact
The complex locomotion act.
But there is more in spinal cord,
Apart from locomotion, stored.
#brainrhymes
But actually, a lot of loops
Have to converge at once.
In spinal cord neuronal groups
Make muscles to relax.
While pushing others to contract
And do it seamlessly, in tact.
These central pattern generators
Operate alone.
While action cortical brain centers
Start and end the stroll.
These actions may appear well-prepped,
Straightforward and mundane.
Of course, it will be so except
When one uses a cane.
While walking, often we, in fact,
With other humans interact.
A set of paired muscle groups
In front and back of legs
Contracts and loosens during walks
Until the walking ends.
The muscles interchange in act,
While ones relax, others contract.
New Matlab toolbox for ECG cleaning. Semiautomatic with user feedback. Good!👍
Actually, I like cleaning the data. It feels like I get to know my participants better. Especially when I look at their cardiac field artifacts.💓
I was lucky to be part of ASPP, Bordeaux in 2021. I learned so much, but more importantly it gave me the confidence and skills to keep going afterwards. It really shaped the path I took, including getting involved in MNE-Python. It’s a great opportunity, the people running ASPP are just the best.
If you want to explore the data yourself, you can filter and recreate figures in the interactive shiny app!

Our review about methods used in Heartbeat Evoked Responses research is out at Psychophysiology ✨!
We hope it will be a helpful resource for the community:

LC activity was found to be different at rest between people with ADHD and controls. But it was lower in ADHD, not higher, suggesting hypo-arousal. LC activity was not related to task performance. Cool!👍 People with ADHD also show larger resting alpha power. Can I jump to the conclusion already?
New paper from my time in linguistics!
The tone in which we say something shapes what people remember - not just what was said (“I want the PIZZA”), but also what was implied (definitely not the salad).
Main result: not everyone will remember it the way you wanted.

True! I guess I want more than I can get with 64 EEG electrodes😄

I tried invertmeeg with P50 EEG data. It was fun🤩!
However, I cannot say I found the perfect method.
Based on the topography, the activity should be from a tagential dipole. Based on previous findings, it should be in area 3b. But I got in the precentral gyrus or on the crown (~area 1).

Thanks! I will take a closer look.
V. important study ❤️
Cool study!👏
As I understand it's about type 2 error (missing a real effect). Can you say something about type 1 error of this particular method based on your simulations?
Structural connectivity between brainstem and cortex. The Substantia nigra (SN) appears highly connected. The Locus coeruleus (LC) is less so. As measured by DTI. Cool!👏
I checked the open data. LC is connected with other brainstem nuclei, including SN, reticular formation, and vestibular nuclei👌.

Happy to share work dissecting the contribution & relative importance of cortical features explaining regional variation in MEG markers using multiv prediction #neuroskyence
Retinal nerve fiber layer thickness (RNFLT) is associated with grey matter density in the occipital cortex and fractional anisotropy in optic radiation. While brain measures correlated with cardiovascular risk factors, retinal measures did not. Cool!👏 I wonder what it feels like to have high RNFLT.
John T. Hale and Team Language Cycles are searching for participants from 25 languages for The Little Prince MEG study. Get in touch via languagecycles.com/home/tlpp/. Eight years and seven rejected proposals in the making, now generously funded by the Johns Hopkins University and the @dfg.de
The dispositions thus reflect
The tendencies around effect.
And then it’s valid to expect
That sometimes powers run in vain.
If it is hard to entertain,
The book that theory explained
In much substantial detail
Is "Getting causes from powers"
By Anjum and Mumford as authors.
#brainrhymes
Among suggestions, there is one
That says it’s causal powers’ sum
That leads to threshold overrun,
And the occurence of event.
By causal power, it is meant
Some properties that represent
The disposition to prevent
Or to encourage the effect.
If cause is just the only breach.
If many causes, count them each,
The causal structure stitch by stitch,
It should be possible to get.
But if we fail despite the sweat,
it’s also possible instead,
Causation doesn’t work like that.
But how exactly does it run?
What does it mean to know a cause
Of heart attack or menopause?
It’s to unravel what's imposed
The ominence of this event.
Because to know is to prevent,
Or the progression curve to bend,
Or cascade to reorient,
With knowledge, all within our reach.
Dense sampling of a few people to study intra-individual variability. Results show that nucleus accumbens BOLD response to reward has low test-retest reliability. Contributing factors are mood and alertness (variability is meaningful). V. cool!🤩 I was reading the introduction and intensely nodding!
People with congenital cataracts can undergo surgery to restore vision. This study examines their white matter using diffusion MRI. Individuals with restored vision show recovery of white matter in visual tracts. Importantly, participants had their cataracts removed relatively late (~8 y.o.). Cool!👏
Dear #Neurofeedback and #Neuroimaging enthusiasts,
Please join us at the rtFIN 2026 (Real-Time Functional Imaging and Neurofeedback) Conference which will take place at the Campus Biotech in Geneva, from October 4th to 7th, 2026.
Submissions are open! Please visit rtfin2026.cibm.ch
Correlation is not causation. But what is causation?
I read another book, "Getting Causes from Powers" by Rani Lill Anjum and Stephen Mumford.

Alpha event-related desynchronization occurs after every stimulus and before the movement. But what neurons do? Is that because of the stimulus, some neurons are recruited, and they leave the oscillatory regime? Or after the stimulus, neurons operate in a completely different fashion? #brainmovies
