How well do classifiers trained on visual activity actually transfer to non-visual reactivation?
#Decoding studies often rely on training in one (visual) condition and applying it to another (e.g. rest-reactivation). However: How well does this work? Show us what makes it work and win up to 1000$!

I always learned a great deal from simulating data (aka mostly how things don't really work the way they are advertised 🙃).
so I can definitely recommend playing with this toolbox for simulating EEG/MEG sources with desired properties (location, coupling) for connectivity. ⬇️

Nick (@willenjoy.bsky.social) is obsessed with signal-to-noise ratio (SNR). And for good reason! It could explain many results. Our simulation toolbox meegsim enables setting up SNR of individual sources as well as SNR of all signal sources with respect to all noise sources.

Do you want to simulate EEG/MEG but don't know where to start? Don't start with ChatGPT, start with *pip install meegsim*.
We (me and @willenjoy.bsky.social) have just released v.0.0.2. Our toolbox generates EEG/MEG using template waveforms with ground truth source activity.

Are you sure that your Heartbeat Evoked Potential (HEP) effect is real?
In our new paper, we show that task-evoked activity can overlap with HEPs, creating false positive effects - unless you correct for it.
