Brain anatomy and molecular signaling predict neurophysiological dynamics across the lifespan www.biorxiv.org/content/10.6... 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

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!👏

Correlation is not causation. But what is causation? I read another book, "Getting Causes from Powers" by Rani Lill Anjum and Stephen Mumford. Read my opinion here www.alinastudenova.com/home/blog/bo...

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

S1 has columnar organization. This study found evidence for it in non-invasive fMRI data for vibrations of 30Hz and 3Hz. There were more nodes (columns of voxels) that responded to 30Hz vibration. Interesting👏! But if there are columns, does it mean EEG/MEG signals don't have a single-layer origin?

Methods research is cool🤩. This work suggests that hexadirectional modulation in fMRI is not a specific signature of grid-cell activity and may arise from alternative mechanisms (variance, nonlinearities, analysis). We need more validation of existing methods, especially for non-invasive recordings.

Important take on the sustainability aspect of open science! Also really liked this related work by Govaart, Hofmann @smnhfmnn.bsky.social & Medawar (2022) doi.org/10.1525/coll...

I have a joke about 1/f slope in EEG/MEG signal, but it's flat.

New eLife editorial: their Publish-Review-Curate model works, even after losing the impact factor. I published with them because I believed in their approach. Scientific publishing needs more courage to embrace change ...especially in times of peer-review crisis.

Last day at #MBB2026 Keynote by Julian Thayer on "Breathing is Fundamental: A Mind/Brain/Body Perspective".

Amazing talk by Ulrike Bingel on expectations "Mind over matter: how expectations shape health and treatment outcomes" #MBB2026 Interestingly, nocebo effects are easier to induce than placebo effects🤔

Absolutely beautiful and comprehensive #keynote by #SonjaKotz on #time and #rhythm processing from a #comparative and #translational #MindBrainBody perspective @ MBB Symposium in Berlin! ✨ band-lab.com @maastrichtu.bsky.social #MBBS2026

So many inspiring talks (here by @saramehrhof.bsky.social, Sameer Alladin, @studenova.bsky.social) and discussions on the first day of the #MindBrainBody Symposium 2026! #MBB2026

@studenova.bsky.social surprised the audience of the #MindBrainBody Symposium with an “embodied presentation” in how absolute post-stimulus alpha amplitude better explains trial-by-trial perception across 5 datasets and 3 somatosensory tasks #MBBS2026

Today I'm at MindBrainBody symposium #MBB2026 Keynote by Karl J. Friston "The physics of affordance"

An interesting way to look at white matter is to measure fiber stiffness using Magnetic Resonance Elastography (MRE). This study shows that stiffness changes with age, more so stiffness parallel to the main fiber direction. Cool!🤩 Combining MRE with DTI surely provides a more comprehensive picture.

Evoked responses in individual participants rarely look like an average over all participants. Does it mean we should have collected more trials? And what if the average from one dataset doesn't look like the average from another dataset? Should we collect more participants? #brainmovies

In this study, a total of 75 neurons in the locus coeruleus (LC) were recorded from 2 monkeys performing a perception decision-making task. My main takeaway is that neuron responses were heterogeneous: there are subpopulations that serve different functions. Cool!👏 But what to do if LC is 4 voxels?

I had been thinking about ways to analyze beta bursts in MEG data. And then I found this paper. Here, oscillatory bursts in mouse V1 were analyzed across 3 dimensions: time, space, and frequency. Results revealed visual-feature-specific burst classes. Amazing!🤩 Exactly what I needed.

I read another book. “In Consciousness We Trust: The Cognitive Neuroscience of Subjective Experience” by Hakwan Lau. Finally, the book about consciousness (=subjective experience) that I can comprehend. Read my opinion here www.alinastudenova.com/home/blog/bo...

Such a cool and rigorous paper by @studenova.bsky.social ! bsky.app/profile/stud...

Another nice example of merging empirical data analysis with computational modelling to gain insights into brain biophysics.

How dynamics arise from the structure is my biggest interest. In this study, we started with a small step and asked how structure constrains dynamics. Spoiler: would that it were so simple… (1/6)

Proprioceptive neurons are found in layer 2/3 of the mouse S1. They are involved in movement execution. This paper shows that without those neurons, the movement will be executed anyway. But the trajectory becomes more stereotyped and less variable. Cool!🤩 Noise in behavioral estimates is not noise.

This paper suggests that in visual statistical learning, associations are better captured when predictability is high in both directions. Dual Factor Heuristic best explains learning effects. Interesting!👍 If a meeting is always on Monday, do Mondays predict meetings or do meetings predict Mondays?

underappreciated concept 🙂 for more dipoles: neighboring dipoles have different orientations & can have different stimulus preferences. so even though topographies look similar, subtle differences remain. maybe that's why it is possible to decode information from relatively few sensors?

The angle of the dipole obviously matters. If active dipoles in two conditions are slightly misaligned, a difference can be observed. However, this difference is not driven by differences in amplitudes, but only by differences in orientations. Here, I simulated such a scenario. #brainmovies

A meta-analysis showing a small but significant association between P300 amplitude and latency and general cognitive abilities (intelligence). The larger and earlier the P300, the more intelligent the person. The elephant in the room, which the authors also acknowledge, is domain-general capacities.

In y/n detection tasks, the internal signal and noise distributions have unequal variance. Instead of using d', we should be using dₐ. dₐ is usually estimated from confidence ratings, but this paper shows (in visual tasks) that it's possible to get dₐ from reaction times. Good news!👏 Will surely try

Woop woop 🎉 Excited to share that our paper has been accepted in Imaging Neuroscience! Can ventral striatal reward signals — originating from deep within the brain — be reconstructed from scalp EEG? We tried to answer this question using deep learning. More soon 👀 Stay tuned.

The water proton spins align With the external magnet field. Magnetization ramping up Such an alignment will yield. The RF pulse then flips the spins To certain number of degrees, The frequency is set as such, They're flipping more or less with ease.

XAI techniques have been proposed as tools to "debug" machine learning models by revealing what they have learned. Challenging this narrative, we find that XAI attributions are strongly dominated by salient features independent of the role of these features for a model. See: tinyurl.com/48m4axnv

V. interesting!⚡ Quote "RSA is not an accurate, direct measure of CNS-generated cardiac vagal activity." RSA - Respiratory Sinus Arrhythmia, the rhythmic change in heart rate during breathing.

LLMs have cognitive biases too, such as confirmation bias, anchoring bias and negativity bias. This survey provides a nice overview. The most interesting and informative part is section with examples.😄

Cool! If this cloud look like a brain, than I'm in motor cortex😄

Nice to see a study addressing mechanisms of evoked response generation! This study obtained that P300 and alpha desynchronization stem from different sources. In the past, I claimed that P300 is partially generated by alpha amplitude asymmetry or baseline-shift mechanism, i.e., they are related.

If oscillations are modulated in amplitude from trial to trial, and those oscillations have a non-zero mean, they "create" an evoked response. It is a baseline-shift mechanism for ERP/ERF generation. Here is a simulated example of how alpha oscillations may generate readiness potential. #brainmovies

Activity-dependent and injury-induced myelination is carried out via different routes. In healthy zebrafish, activity-related plasticity was linked to recently proliferated oligodendrocyte precursor cells (OPCs). But during demyelination, OPCs without prior proliferation were also recruited. Cool!👍

Energy pathways from whole-brain transcriptomics have certain spatial distributions. 4 out of 5 maps look similar, while pentose phosphate pathway looks different. Interesting that energy maps only partially agree with PET data. Nice!👏 I wonder how those maps correlate with vascular architecture.

I read a book. “Superintelligence: Paths, Dangers, Strategies” by Nick Bostrom. It's from 2014, but very much present-day. Read my opinion here www.alinastudenova.com/home/blog/bo...

LC - a tiny structure Located in midbrain; Observed in MR image, Quite clear on axial plane. Produce it noradrenaline Attention to sustain, And after night of sleep Arousal to regain, To manage more proficiently Emotional domain, And somewhat plausibly A memory to retain.

Amazing workshop "Panpsychism, Non-Physicalism and the Causal Powers of Consciousness" with Prof. Hedda Hassel Mørch on her recent book organized by Tobias Schlicht (wait, what?) at Ruhr-Universität Bochum and also online at www.pe.ruhr-uni-bochum.de/philosophie/... V. interesting!🤩
