However, despite achieving correlations higher than other ML-based models, there’s still room for improvement.
Stay tuned to see how far we can push EEG-based decoding of striatal reward signals in future work!
The model’s predictions also showed anatomical specificity (ventral striatum) and functional validity (win-loss modulations).
Results show promising predictive accuracy: the model-derived predictions correlated with the true fMRI BOLD timeseries at mean r = 0.32.
In this work, we trained a CNN (based on Kovalev et al., 2022) to predict ventral striatal fMRI-BOLD signals from simultaneously recorded EEG.
Here we gooo!
Will fMRI become obsolete for measuring striatal reward signals?
Probably not anytime soon…
Still, in our latest paper, we use AI to take a step toward decoding striatal reward signals from EEG — maybe nudging the fMRI monopoly just a little :)

Such a cool and rigorous paper by @studenova.bsky.social !

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)
Scientists no Longer Find Twitter Professionally Useful, and have Switched to Bluesky academic.oup.com/icb/article-...
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.
On #InternationalDayOfWomenAndGirlsInScience, this article hit me: more children are drawing scientists as women than ever before. Yay! 🎉
🤔 But still only ~30%.
Progress, yes.
Equality, not yet.

@cbsopenscience.bsky.social great opportunity to connect over open science in Leipzig coming up!
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.

I have been trying to simulate event-related alpha amplitude decrease with the Jansen-Rit model. Turns out adding external inhibitory input abolishes alpha. Pretty obvious. But how does it agree with more alpha = more inhibition?

Heute noch Thema Vereinbarkeit (Familie & Beruf). Das ist mir auch deshalb wichtig, weil ich selbst als Doktorandin so gut wie keine Professorinnen mit Kind(ern) als Vorbild hatte, mir das aber gewünscht hätte. Meine Karriere sieht auf dem Papier jetzt wie ein "Vorzeigemodell" für Vereinbarkeit aus.
main goal for this year: find a new job! 🙂
looking for a role with fun & complex technical challenges & within a great community. my main expertise is in signal processing/EEG/MEG, but topic-wise I am quite flexible.
science/industry both great! starting mid-year. nschawor.github.io/cv
The Max Planck Society has begun an exploratory round table for open science. We are drafting some recommendations to leadership. Still a long way to go! But here are my notes on the most recent draft, just so you all know how I am trying to steer things.
It’s not too late to apply for the PhD position in my lab! Please send your documents (cover letter, CV, transcripts, names of references) through the official application platform by Nov 25!
Please share! - 🚨⚠️ PhD position alert ⚠️🚨 - Please share!
Come work with @ldeserno.bsky.social and yours truly on an exciting DFG-funded project on the neurocognitive mechanisms of (noise in) learning and decision-making in development and ADHD!
Is overeating driven by hedonism? @danasmall.bsky.social &co argue that the pleasure of eating food is not a driver of the #obesity epidemic, but rather the regular consumption of an unhealthy diet blunts sensitivity to interoceptive signals that drive food reward #neurosky 🧪

Big shake-up for dopamine theory?
This new @NatureComms paper argues that VTA dopamine isn’t signaling reward prediction error but instead modulates force and performance.
If true, it decouples learning from motivation and puts pressure on decades of RPE-based models.

Fresh from the press 🍃
In this article, we put forward a framework for understanding goal-directed and habitual control. We propose how interactive loops in the brain & shortcuts between them may shape our behavior – and that of Transformers. Looking forward to your thoughts💡

Functional connectivity (FC) is driven by 1/f. The approach: compute FC as usual, compute FC only with ROI where oscillations are 'present', then compare. Alpha lives, but not other bands. Idk, seems overstated. If beta comes in bursts: no peak, but could be FC
