Using cluster-based permutation tests to estimate MEG/EEG onsets: how bad is it?

https://www.biorxiv.org/content/10.1101/2023.11.13.566864v1

Actually not bad at all: even if you don't follow the statistical orthodoxy, onsets estimated using cluster inferences are more accurate in the long run than using other standard methods. But all methods used to localise in MEEG research rely on a statistical interaction fallacy, maybe we can do better?

Many choices are linked to a specific motor action, but we can also make choices independent of the actions used to implement them. Our paper asking whether such abstraction is a general property of human decision-making is finally out: https://journals.plos.org/Plosbiology/article?id=10.1371/journal.pbio.3002324 @PLOSBiology @neurobuzz @neuroscience

#Meta sharing new research that brings us one step closer to real-time decoding of image perception from brain activity https://ai.meta.com/blog/brain-ai-image-decoding-meg-magnetoencephalography/ #AI #MEG #neuroscience; more information on Twitter/X at https://twitter.com/AIatMeta/status/1714635316554772716

We often ask to what extent neural representations generalize across contexts - e.g., across time, experimental conditions, or between task variables. Using multivariate cross-decoding, we check whether a decoder, trained in one context, returns significant results in another context. In our new article (with Markus Siegel - and my first, and quite possibly last, in NeuroImage: https://www.sciencedirect.com/science/article/pii/S1053811923004093), we show that this approach is prone to false positives when applied to neural population data involving any signal mixing, such as M/EEG, fMRI, ECoG, LFP. #neuroscience #NeuroPapers #decoding #mvpa #eeg #meg #fmri #neurophysiology #electrophysiology #NeuroMethods @neuroscience @neurobuzz (1/7)

[preprint alert 🚨 link below] How do we search for elements within a cognitive map? How does the brain perform search, are elements reactivated in sequence or simultaneously? We set out to answer this question using MEG and decoding

We let participants learn associations that were embedded into a hidden graph structure. After a short consolidation (8 min.) we asked them to retrieve triplets from the hidden graph.
We trained a machine learning classifiers to extract representations from #MEG recordings of the individual items per participant. Using these classifiers, we assessed during retrieval whether items were replayed in short sequence or were reactivated simultaneously.

We confirmed that near items are stronger reactivated than items further away. Looking at this relationship in detail revealed that there was a grading of items on the graph by their decoded reactivation strength, only present for correct answers. (4/7)

Additionally, we also looked into sequential replay using #TDLM. We found that overall there was no significant sequential replay detected (5/7)

However, there was a significant correlation between replay and memory performance with low-performing participants relying more on sequential replay. This is in line with previous results from

👀 Helloooo 👋🏼

#introduction update for Oct 2023!

😊 I’m excited to be here! My name is Megan, I currently work with #magnetoencephalography #MEG data as a post-bacc in a #neuroscience lab, with hopes of eventually pursuing #Neuropsychology. 🧠

💻 I’ll post about #data (especially wacky data), #SciComm, or about an organization I’m volunteering for, depending on the day.🎗️

Thanks for having me! 💕

Big news for the #mri #fmri #eeg #meg @fmri communities

Hi hive mind, I'm looking for studies that explore time-of-day effects in resting-state electrophysiological activity (#EEG, #MEG, intracranial). If anyone has any resources or open access datasets to share, please let me know! #neuroscience #neuroimaging #research #reproducibility

New instance, new #introduction :) I moved to neuromatch.social as it seems to match my interests more closely.

I'm a PhD candidate working at the intersection of #sleep, #memory and #MachineLearning. I'm currently on a mission to uncover #MemoryReplay and #MemoryReactivation in humans using #MEG data. Besides that I'm a #python enthusiast, #OpenSource advocate and I think #OpenScience is the proper way to do science. I'm doing all of that at the Central Institute of Mental Health with @GordonFeld

Just moved to neuromatch.social, so here it goes (again), #introduction :

Hi everyone, I'm a last year undergrad in #Neuroscience & #ComputerScience at McGill. I'm doing #ComputationalNeuroscience research in the Baillet Lab at The Neuro (MNI), focusing on whole-brain dynamical models of coupled neural masses calibrated to #MEG #Neuroimaging data (more details @ https://neurolife77.github.io/ if anyone is curious).

I am also the VP of the #MachineLearning committee at PharmaHacks, a hackathon that blends #Biology & #DataScience with a focus on #Pharma.

------------------------ Bonus ------------------------

Since I have the space to put it in the same post now, thanks to the freedom in post length from this new server, here's a bonus:

I regularly share links to preprints that catch my attention and tag them with: #arxivfeed

I started doing this because I thought that the arxiv bots on mastodon not super efficient, but after doing it for about a month I'd say it's also a good way to keep some form of history of my nightly exploration of the literature in my fields of interest. I usually share stuff about #ComputationalNeuroscience, #Neuroimaging, #DynamicalSystems, #MachineLeaning, #ArtificialIntelligence, etc.

Disclaimer: I usually only read the abstract or skim through them at the time of posting.
Disclaimer 2: I am definitely not consistent.

Hi,
I am Thomas. I am a #neuroscientist working with #MEG at the University of Salzburg. I do a lot of methods and code development (check out https://o-ptb.readthedocs.io) and mainly auditory research.

I also arrange #acapella music and publish one-man-acapella videos of these.

Hello World! another #introduction

I'm an Asst Prof at the Centre for Human Brain Health, Uni of Birmingham UK. My research combines #cognitiveneuroscience (#MEG, #EEG), maths and #foss to explore #oscillations in the brain.

I develop a couple of #python packages for time-series analysis and try to contribute to more #openscience #opensource

Next projects are a method combining spectrum estimation with regression and population variability in oscillatory metrics... stay tuned!
