ok, imagine you have an oscillation that is not symmetric around 0 (small direct current shift) with some amplitude modulation, for instance with 1/f-dynamics.

➡️ then these 1/f-dynamics will show up in low frequency part of spectrum (red); in addition to around oscillation peak (yellow).

I find this paper really confusing. There are several measures (power, coherence, network communication, information based statistical dependencies) which are all measures of the "behavior" of the system, and definitely share similarities. Yet some are considered "mechanisms" underlying the others.

We show that an intrinsic motivational learning signal (information gain) is encoded through synergistic and higher-order functional brain interactions and is broadcast to prefrontal reward circuits.

There are some corners of the network science literature which adamantly claim that connected components *must* belong to different communities. Yet, ER networks can easily be disconnected, and the same is true for individual groups in SBM networks. There, splitting the components overfits. 1/4

"The analysis of the L.L.M. users showed fewer widespread connections between different parts of their brains"

This is goddamn embarrassing, man. Instructive for understanding just how bad media is on this. Like there are anatomical changes being measured.

happy that our article about mu & alpha rhythm waveform shape in development is now finally out in the open: doi.org/10.1162/jocn...

oscillation frequency changes across development (one of the most robust findings in the oscillation world). in this work, we also look at waveform shape changes.

the level of misinformation sparked because of this bananas EEG preprint is just really tragic.

By the way if you think that a researcher caused cognitive decline to happen to participants in a study you should probably be freaked out by that

Localizing synergies of hidden factors across complex systems: resting brain networks and HeLa gene expression profile as case studies

arxiv.org/abs/2506.09053
Localizing synergies of hidden factors across complex systems: resting brain networks and HeLa gene expression profile as case studies Marlis Ontivero-Ortega, Gorana Mijatovic, Luca Faes, Daniele Marinazzo, Sebastiano Stramaglia Factor analysis is a well-known statistical method to describe the variability of observed variables in terms of a smaller number of unobserved latent variables called factors. Even though latent factors are conceptually independent of each other, their influence on the observed variables is often joint and synergistic. We propose to quantify the synergy of the joint influence of factors on the observed variables using the O-information, a recently introduced metrics to assess high order dependencies in complex systems, in a new framework where latent factors and observed variables are jointly analyzed in terms of their joint informational character. Two case studies are reported: analyzing resting fMRI data, we find that DMN and FP networks show the highest synergy, consistently with their crucial role in higher cognitive functions; concerning HeLa cells, we find that the most synergistic gene is STK-12 (AURKB), suggesting that this gene is involved in controlling the HeLa cell cycle. We believe that this approach, representing a bridge between factor analysis and the field of high-order interactions, will find wide application across several domains.

TLDR, when multisensory signals vary over time, neural architecture becomes important. Biggest not always best.

Quick check of the paper mentioned here under and it's rather "opaque". 🤔

Key point IMO is confusing Maxwell's equations time dependence and brain waves time scale. Anisotropy and inhomogeneity in tissue conductivity is important but it lives very well with the "quasi-static approximation".
