Are brain rhythms a steady hum or a brief buzz? Both. Alpha and beta activity are relatively sustained, helping maintain ongoing brain state, supporting its role in top-down control. Universal rhythmic architecture uncovers two modes of neural dynamics www.nature.com/articles/s41... #neuroscience

Universal rhythmic architecture uncovers two modes of neural dynamics - Nature Communications

Brain oscillations are traditionally regarded as sustained rhythms. Here, the authors show that there are both high and low-rhythmicity bands, characterised by brief bursts, which can signal responses...

We put out this preprint a couple months ago, but I really wanted to replicate our findings before we went to publication. At first, what we found was very confusing! But when we dug in, it revealed a fascinating neural strategy for how we switch between tasks doi.org/10.1101/2024.09.29.615736 🧵

Convergent neural dynamical systems for task control in artificial networks and human brains

The ability to switch between tasks is a core component of human intelligence, yet a mechanistic understanding of this capacity has remained elusive. Long-standing debates over how task switching is i...

Harrison Ritz@hritz.bsky.social · 2y ago

🎉New project 🎉 doi.org/10.1101/2024... How do we navigate between brain states when we switch tasks? Are dynamics driven by control, or passive decay of the prev task? We shed light on this classic debate by comparing high-d linear dynamical systems fit to EEGs and RNNs during task-switching 🌀

OK folks, this is a very convincing EEG artifact rejection method both theoretically and practically from my short experience. It's the only method I tried that gets rid of pervasive artifacts in a dataset I'm currently analyzing!

New paper, on a worrying trend in meta-science: the practice of anonymising datasets on, e.g., published articles. We argue that this is at odds with norms established in research synthesis, explore arguments for anonymisation, provide counterpoints, and demonstrate implications and epistemic costs.

Wahou, so refreshing this first day at the meta-science conference #PSE8. How did I change my mind from science is broken to yes but great minds are working on it! I also received very positive feedback on my work on outlier detection (that should be out as a preprint soonish)

Now Aurélien Allard with the second talk of #PSE8: How is it possible that there is massive scientific progress, even thought there is a lot of scientific error?

A hypothesis developed based on the data is often more likely to be true, than if you had not used the data. The problem is not whether the hypothesis is true. The problem is the hypothesis was not severely tested. You can't *claim* it is true until you test it on new data.

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

Interesting, and good recommendations that apply broadly « Increase methodological rigour: increase sample sizes; pre-register analyses; use transparent, harmonised pipelines; validate models externally; share data and code; and publish null results.» www.cambridge.org/core/journal...

It seems massive but I am not a fMRI expert. They seems to report that the relation between bold signal and neural engagement is not straightforward, and can even be reversed. So increase bold = increase vascular activity, but not necessarily increase neural activity www.nature.com/articles/s41...
