Our paper on single-trial #EEG / #MEG with hidden multivariate patterns is now accepted in #Imaging #Neuroscience 🥳🥳

Reviewers were very helpful to make the manuscript clearer and more convincing 🥹

Dear editors of #DiamondOpenAccess journals,

I'm more than available as a reviewer for the topics of #EEG #Decision #psychophysics #chronometry #EMG

I would also be ready to do public post-print reviews for initiatives such as Open Research Europe.

I think this method is filling a very deep need for #cognitive #neuroscience researcher using EEG/MEG as single-trial time estimates are not only desirable but absolutely necessary (see Figure 2 of the preprint). I tag along some people that I think would be interested

In the paper we show three example applications on publicly available datasets:
- the P3
- the N2pc
- and a #decision-making dataset

We show how the exploratory decision-making dataset contains the same component as the N2pc and the P3 dataset, therefore arguably measuring single-trial potentials relating to attentional orientation and decision-making!

This method basically turns any ERP experiment into an estimated collection of half-sines with different time and spatial representations.

This highly changes the representation of an average ERP as there is (ideally) no more time-jitter as we can center on event time at each trial.
See this example where, for a simulated electrode, we only inserted half-sines in the time-series of each epoch (left plot), plot the average stimulus centered ERP (top) and the HMP-event centered ERP (bottom)

The hidden multivariate pattern method (HMP) assumes that single trials events in the E/MEG signal are 1) coherent transient topographies recurring across trials 2) in sequence after stimulus onset up to the response (e.g. visual before motor) and 3) that the time distances between events (loosely) follow a probability distribution.

HMP then estimates the number of events needed and their topographies and time distributions to get the probability of each event at each time point in each trial

TLDR: with the hidden multivariate pattern method (HMP), using a few assumptions and the E/#MEG signal during the reaction time, we can:
- recover how many task related events appear in the #EEG
- get their SINGLE-TRIAL time location and therefore also voltage activity 🤯

Dear #eeg community I need your help!

In the review process of our paper on single trial ERPs (https://www.biorxiv.org/content/10.1101/2024.02.13.580102v1) we are looking for a nice public dataset with:
- EEG or MEG
- Reaction times based task (max around one second)
- preprocessed (preferably with MNE)

Any ideas? For now, I see LIMO and ERP-core, but I'll only create the #MNE pipeline if I don't have other choices...

I am planning a course on mental chronometry and would like to open the course with an interactive part.

Does anyone know of an online plateform (e.g. wooclap) allowing to record the reaction time of the students? That would be a nice opening to RT distributions.

I guess I could always use online experimenting plateforms but I don't know any allowing an easy connexion and a rapid collection of the results 😔

I accepted to review a paper for an #elsevier owned journal two weeks ago. Seeing the recent amazing move of #Neuroimage editorial board (see boosts), I am wondering whether I should still give this review to be nice to the editor and the authors or whether I should withdraw from my role to protest and also encourage editors/authors to stop dealing with #Elsevier journals 🤔

#Obsidian note taking is just plain awesome. I've been struggling to have a decent planning tool on Linux, but now I finally feel organized 🥹

Takes a bit of learning but is completely worth it, stores note in .md format (possibility to synch with subscribtion), todo list management with #tasks obsidian manager, easily link your different notes... and probably so much more

- Which publishing company should we DDOS with #papers?
- Can I DDOS my resume for future hiring committees to not look at the number of lines in it?

Other ideas welcome 😀
