🚀New paper out! With @lauradugue.bsky.social & @kirstenpetras.bsky.social, we show that traveling waves seen in EEG/MEG sensors might reflect real waves on the brain’s visual cortices—not just artifacts. Based on a MEG-EEG dataset with visually triggered traveling waves.

Our model is specific to conditions (directions of traveling waves, standing waves) and wave parameters (temporal and spatial frequencies).

👀Worth noting:
Simulating waves in just V1 had an effect on all sensors—even the ones far away. This shows how localized TWs can create widespread patterns in MEG/EEG.

🔍Proof of concept:
We used visual stimuli carefully designed to elicit traveling waves in V1. Participants viewed these while we recorded simultaneous MEG/EEG, giving us a ground-truth dataset for detecting traveling waves.

💡Our solution:
Using an encoding model, we simulate traveling waves in V1 → project them into sensor space → generate predicted MEG/EEG signals.

🛠️The challenge:
Traveling waves (TWs) are everywhere in brain recordings... But they're almost always studied with invasive methods at the mesoscopic scale — within regions like V1. Why? MEG/EEG's coarse spatial resolution makes TWs hard to detect.

🎓Bringing greater diversity could create a different academic system, one that would spark vocations, enable a better work-life balance, and foster supportive mentoring... which would benefit the whole community! More info ➡️https://www.jneurosci.org/content/42/24/4769.abstract

The problem? Race, socio-economic status, and gender all contribute to individual differences in brain structure and cognition. This means we could be missing a significant part of the story... More info ➡️https://nyaspubs.onlinelibrary.wiley.com/doi/abs/10.1111/nyas.14268

🧠Cognitive neuroscience aims to understand how the brain thinks and functions, yet much of our knowledge comes from studies conducted on a highly biased population—primarily healthy, young, white men.

The simple answer is that it would increase diversity! But beyond the social and ethical aspects, does it actually impact scientific research? In my field—cognitive neuroscience—the answer is definitely yes! It influences both how research is conducted and the research itself.
