So the only important thing for us from the MPMs was 0.8mm resolution. For non-laminar recon I think that resolution would still improve things based on the cortical surfaces we've gotten at 1mm vs 0.8mm. I'm not a freesurfer wizard though - this is just with default recon-all settings. YMMV

That's a wrap on #NeuroFrance2025 !

DANClab is at #NeuroFrance2025 in full force! @quentinmoreau.bsky.social @hollyrayson.bsky.social
Tomorrow at 9h30 I'll give a talk about the cool methods we've developed to analyze beta bursts

Post a photo you took with no context to bring some zen to the timeline

This method outperforms power-based approaches using either just the beta or mu and beta frequency bands in terms of accuracy and information transfer rate

Sotirios's new paper topples the ruling power, using convolution of neural time series with waveform kernels for fast online burst detection and the common-spatial pattern (CSP) method to extract burst spatial features.
December 18, 2024 at 12:56 PM
With Sotirios & Jeremie, we then showed that beta bursts question the ruling power for BCI, demonstrating that waveform-specific burst rates are informative for motor imagery decoding

We've shown in previous work that beta bursts have diverse waveform shapes, and that bursts with different waveforms have different rate dynamics

The result is a nice estimate of rhythmicity at every frequency, with a spectrum that matches the PSD. We show that this method is sensitive enough to detect group and condition differences, changes with sensorimotor learning, and relationships with behavior that lagged Fourier autocoherence can't
December 10, 2024 at 12:23 PM
We came up with a simple idea: Gaussian multiplication in the frequency domain for bandpass filtering, Hilbert transform to get continuous phase and amplitude, and compute lagged coherence at each time point. Surrogate data from an autoregressive model handles the suprious amplitude correlations
December 10, 2024 at 12:23 PM

Lagged (auto)coherence is a great tool, and we use it a lot in group, but you may have noticed some odd things: peak freqs don't match the PSD, lots of spectral spread, and weird aliasing effects at high frequencies and lags.

Have you been wanting to dive into laminar MEG, but have been held back by using windows? We've got you covered! laMEG now tested on windows!

Thanks to @quentinmoreau.bsky.social, Maxime Ferez, and Ludovic Darmet!

Also check out Holly Rayson's poster (186) to see how with movement compensation and high-res MRI, we can even do this with infants!!!

Come and check out my talk at 16:00 on Wednesday at
BioMag 2024 to hear all about this and get a sneak peak of how we're using this to look at laminar dynamics in visual and sensorimotor areas
August 25, 2024 at 11:46 PM
Maybe you don't care about laminae, or maybe you still don't believe in laminar MEG. But here's something for everyone: laMEG includes SPM compiled as a python library! It automatically installs the MATLAB runtime env too - no license required, and easily run on a cluster
August 25, 2024 at 11:45 PM
We've also extended the model comparison and ROI power laminar analyses to work across an arbitrary number of intermediate layer surfaces
August 25, 2024 at 11:44 PM
laMEG provides all the post-processing required to perform laminar inference from FreeSurfer-generated surfaces with an arbitrary number of intermediate layer surfaces
August 25, 2024 at 11:42 PM
We later extended this to the temporal domain to look at laminar dynamics

August 25, 2024 at 11:42 PM
We've previously shown how to perform laminar inference with MEG using model comparison based on free energy or cross-validation error
sciencedirect.com/science/arti...
as well as in terms of changes in freq-specific power in an ROI

🚨New laminar MEG toolkit🚨I'm so happy to be at
@biomag2024
to announce the release of laMEG, an easy-to-install implementation of the simulations and analyses from our laminar MEG papers github.com/danclab/laMEG

My group got me a birthday cake of my spirit animal. Thank you DANC lab! Couldn't ask for a better bunch
January 26, 2024 at 4:14 PM
I'm so pleased to be in Dublin for #MEGUKI2023 where I'll be giving my first keynote. If here you're here, also check out
@maciekszul.bsky.social and Siqi Zhang's posters!

Finally, Sotiris Papadopoulos will also give a talk at the satellite about how we're using all of this for fast and accurate non-invasive BCI in collaboration with Jeremie Mattout
