#brainrhymes Everybody everyday Sleep and eat, and on the way, But also, whether want or not, they play. There are a lot of daily games, For some, to open counter race, For some, to win an argument or other chase.

Interventions in LLMs are aimed at steering the model's responses in a certain way. This paper proposes an intervention method that changes the behavior of an LLM by modifying only about 0.01% of its neurons. Nice!👏 Of course, only open-source (open-weights) LLMs were investigated.

To be fair, Anthropic didn't say Claude is conscious. But I'm missing on the point why the found J-space is a global workspace and not just massive working memory?

In near-threshold research, we determine individual detection threshold by testing a range of stimulus intensities and fitting a sigmoid (psychometric curve). Here, I simulated effect of the slope: it affects trial-by-trial consistency in detection and reliability of initial estimation. #brainmovies

Some neurons fire during certain phases of LFP oscillations, while some fire more when LFP oscillates at certain frequencies. V. cool!🤩 I appreciated the discussion about causality: do oscillations in LFP cause increased spiking, or does the change in spiking cause changes in the spectrum of LFP?

Diffusion-weighted MRI across multiple time points. Mean diffusivity was found to change in real time during learning. Nice!👏 But how much of this is microstructural remodeling? It's all water movement, and recently I learned that glymphatic-related processes may contribute to diffusion MRI signal.

My search for the theory of consciousness with the fewest problems led me to the higher-order thought (HOT) theory. I read the book “Consciousness: Essays from a Higher-Order Perspective” by Peter Carruthers. Nope, search will continue. Read my opinion here www.alinastudenova.com/home/blog/bo...

OHBM 2026 Photo Recap 📸 Thank you to every attendee, presenter, volunteer, exhibitor, sponsor, and partner who made this year's Annual Meeting such a success. Take a look back at some of our favorite moments and we'll see you in Toronto for #OHBM2027! #OHBM2026 #Neuroimaging #BrainResearch

It was my first #OHBM2026, certainly not the last😍😍😍 Great section of talks, amazing posters, lovely people! Thanks a lot to the organizers!

Today's keynote at #OHBM2026 is Dr. Vitória Piai about language. Language is not my jam, but Dr. Piai addressed several common issues that I was able to relate.☺️ For instance, the abstraction problem: "no two instances of 'the same' biological mechanism are physically identical".🤔

A career advice at #OHBM2026 from Dr. Vince Calhoun. It seems to me that it is not just academy career advice but in general life advice.👍 Among other points: - paper is a progress report not a final monument - you are more than your last result - luck favors the prepared

Highlight of today at #OHBM2026 is symposium on voluntary movements and sense of agency, honoring Mark Hallett's work. In particular, the focus is on disorders of movement, such as functional neurological disorders, distonia and Parkinson’s disease tremor.

Amazing keynote at #OHBM2026 by Dr. Nanthia Suthana "Mapping the Human Brain in Naturalistic Environments".😍 Theta bouts in invasive hippocampal recordings in humans. Proposed framework: theta bouts reflect internal search processes that occur when retrieving memory, especially under uncertainty.

First day at #OHBM2026 My poster is tomorrow. Meanwhile there are educational courses. Particularly interesting is "Neuroanatomy and its impact on structural and functional imaging"😍

It was widespread in the past, but even now some use just one EEG electrode in the sensor space for analysis. Here I plotted leadfield from C4 for different participants in the LEMON dataset. Heterogeneous🤔. Individual MRIs are used for the forward model, but the montage is standard. #brainmovies

Today I had an amazing opportunity to listen Philip talking about this study. Elegant design and cool analysis aiming at disentagling different neural contributions to natural scene viewing.👏

Amazing workshop on C-tests (tests for consciousness)😍 www.uni-bamberg.de/en/bamxi/res...

Excited to share “Timing Matters: Leveraging Positron Emission Tomography Imaging and Hormonal Cycles for Precision Psychiatry in Female Mental Health” is published in Biological Psychiatry! 🎉

It’s found below the thalamus, Above substantia nigra, Next to internal capsule, A part of basal ganglia. It functions like the ‘brakes’ To our motor system, Free movement regulates And acts as a resistance.

Analyzing sharp-wave ripples with different approaches produces different results😑. Same for directed functional connectivity😑. And that was from SUA and LFP from rodents. It is probably the same with beta bursts and coherence in EEG/MEG. Probably, we should do multiverse analyses more often🤔.

Modeling preprint. Recurrent inhibition (I-I connections) stabilizes the network in the sense that it is less sensitive to input variations or connectivity changes. At the same time, recurrent inhibition diminishes PING-like gamma oscillations. Interesting!🤩 I wonder if it relates to alpha rhythm.

New preprint from down under: Can acute TMS effects on dynamic brain states predict subsequent symptom change during treatment for depression? www.biorxiv.org/content/10.6... #restinstateEEG #TMS #Depression #HMM #longitudinal

I read another book titled “Out of Our Heads: Why You Are Not Your Brain, and Other Lessons from the Biology of Consciousness” by Alva Noë. Idk (≖_≖ ). A sensorimotor account of perceptual consciousness is not my cup of tea. Read my opinion here www.alinastudenova.com/home/blog/bo...

Averaged-over-trials evoked responses (ERPs) also have frequency content. Here, I'm exploring P50 after somatosensory stimulation. I computed the power of the already averaged ERP (also known as "evoked power") using wavelets. P50 has frequency in the alpha-lower beta range. #brainmovies

Fingertip receptor fields (RF) in the across-width-of-finger direction are represented along the superior-to-inferior axis in BA3b. RFs in the along-finger direction do not show a topographic gradient in BA3b. Cool!👏 Even more interesting is that RFs are quite large, in the MEG resolution range.

Smell seems to be outside in the world and spatially indeterminate. This paper argues that it becomes minimally spatially determinate if we add 1) bodily parts (smell is at the nose), and 2) tactile sensations from sniffing. So smell is spatially vague but still related to a bodily location. Cool!🤩

[1/4] Super happy to have contributed to this marvellous book "The Scientific Study of Consciousness: Experimental and Theoretical Approaches", led and curated by Lucia Melloni and Umberto Olcese! All chapters are now available online: www.horizon-minds.com

What happens when your specparam model specification doesn’t match your actual neural signal? I built a small WASM Python app to explore on simulations how model misfit can skew PSD shape and parameter estimates. Try it online here: danielborek.me/code-spectra... #EEG #MEG #Python #shiny

Today I'm at Applied Causal Graphs workshop🤩 . So cool! DAGs are definitely underrated in neuroscience.

This opinion claims that the brain is suboptimal. Singular optimality is impossible due to complex phylogenetic (species) and developmental (individual) trajectories. Instead, the brain's organization is shaped by trade-offs. Not sure if it helps or hurts the field, but simple solutions rarely work.

Beta ERD/S and beta bursts reflect skill learning across a multi-session bimanual coordination task. Nice to see ERD/S and bursts being compared in the same study👏. Except the comparison is purely descriptive, why not statistically test them against each other to see which better explains behavior?

To be a scientist means you walk Alone, in darkness, in the fog. There are no landmarks in your sight, No cues to turn to left or right. Sometimes you stumble on a peer, Who's just as lost as you appeared. Together you then carry on Along the path to the unknown.

New preprint from a fun collab spanning two continents: www.researchsquare.com/article/rs-9...

Individual MRI source reconstruction didn't outperform template heads for prediction of cognition in Parkinson’s disease. Prediction was based on EEG functional connectivity. Not going to defend individual heads viciously, but functional connectivity is dubious overall without controlling for SNR.🤔

Thanks for your comments Valentin, much appreciated - and thanks as well for sharing the data publicly! A few thoughts on your points 👇

Representational drift is when neurons change tuning across days. So individual neurons drift, while population geometry remains stable. This paper shows that drift is 1) coordinated across regions; 2) is somewhat correlated with behaviour, but 3) persists after controlling for behaviour. So cool!🤩

This is the May cover of NN but it has already been debunked on biorxiv www.biorxiv.org/content/10.6... Such a clear statement about the ridiculous pace of publishing (not just NN).

I'm trying to make sense of spaces for source reconstruction (EEG or MEG) and brain anatomy (from MRI). In a way, I'm exploring possible sources of variance. Leadfield gain = column norm. Curvature = concave or convex. LGI = how folded the cortical area is. #brainmovies

I live under a rock! There are so many methods for the extraction of oscillatory bursts, and, in our lab, we use one🤪 V. useful guide👇

Hello Bluesky! Below this post, you will find all my very interesting "new paper" threads. 🤓 Note that some of these are much older than the timestamp because I rescued them from Twitter to make them accessible for everyone.

Controllability is based on BOLD and shows whether a region influences whole-brain state transitions. In this study, thalamic controllability was largely independent of structural measures. Also, controllability explained cognition better. Nice!👏 But maybe structural measures taken were imprecise.

Super cool project😍! And I over the weekend crocheted basal ganglia.

You’re breathing in and breathing out, Without thinking much about. The basic rhythm of your breath Medullar centers generate; While breathing rate and breathing depth From pontine nodes originate.

Emergence is an attractive theory. It's natural. In this preprint, the author develops an idea of emergent agency. An interesting read🤔, and it could work well for someone predisposed towards other emergence ideas. For me, I cannot shake the feeling that I need to know how *exactly* it emerges.

Recently Epp et al. Nat. Neurosci. (2025) showed that BOLD signal correlates both positively and negatively with metabolism (when expected only positively). This preprint shows that metabolism estimates from Epp et al. are noisy and uncertain, which might have driven the sign reversal. Insightful!👏

One of my interests is movement. So I decided to educate myself and read a recent comprehensive overview of the motor system, packed into a book titled "The Brain in Motion: From Microcircuits to Global Brain Function" by S. Grillner. Recommend👍! My short note www.alinastudenova.com/home/blog/bo...

Basic but may be missed. It is possible to detect differences in the amplitudes of evoked responses using a cluster-based permutation test, which is, in reality, just a difference in latency. Also interesting, of course, but could be interpreted in a different manner. #brainmovies

Functional connectivity from fMRI revealed patch-like chains, especially in associative cortices (like PFC). These chains span across multiple different cytoarchitectonic areas. Cool!🤩 Like the individualized approach. Sadly, cytoarchitecture cannot be individualized, yet. V. informative thread👇
