Can we move MEG a little further down here now? Nobody puts Baby in a corner!

Our group has been looking at beta bursts for the last 5 years, but we do it a little differently than most - we group into types them based on their waveforms. In this open access article we lay out why and what we think this might mean journals.sagepub.com/doi/10.1177/... #neuroskyence

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

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.

Decision, Action, and Neural Computation (DANC) lab @danclab.bsky.social · 18/12/2024

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 iopscience.iop.org/article/10.1...

Decision, Action, and Neural Computation (DANC) lab @danclab.bsky.social · 18/12/2024

We've shown in previous work that beta bursts have diverse waveform shapes, and that bursts with different waveforms have different rate dynamics www.sciencedirect.com/science/arti... www.jneurosci.org/content/43/4...

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

Decision, Action, and Neural Computation (DANC) lab @danclab.bsky.social · 10/12/2024

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

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.

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

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

We've also extended the model comparison and ROI power laminar analyses to work across an arbitrary number of intermediate layer surfaces
