It's been a while since our last laminar MEG paper, but we're back! This time we push beyond deep versus superficial distinctions and go whole hog. Check it out- lots more exciting stuff to come! 🧠📈

🚨🚨🚨PREPRINT ALERT🚨🚨🚨
Neural dynamics across cortical layers are key to brain computations - but non-invasively, we’ve been limited to rough "deep vs. superficial" distinctions. What if we told you that it is possible to achieve full (TRUE!) laminar (I, II, III, IV, V, VI) precision with MEG!

Overview of the simulation strategy and analysis. a) Pial and white matter boundaries
surfaces are extracted from anatomical MRI volumes. b) Intermediate equidistant surfaces are
generated between the pial and white matter surfaces (labeled as superficial (S) and deep (D)
respectively). c) Surfaces are downsampled together, maintaining vertex correspondence across
layers. Dipole orientations are constrained using vectors linking corresponding vertices (link vectors).
d) The thickness of cortical laminae varies across the cortical depth (70–72), which is evenly sampled
by the equidistant source surface layers. e) Each colored line represents the model evidence (relative
to the worst model, ΔF) over source layer models, for a signal simulated at a particular layer (the
simulated layer is indicated by the line color). The source layer model with the maximal ΔF is
indicated by “˄”. f) Result matrix summarizing ΔF across simulated source locations, with peak
relative model evidence marked with “˄”. g) Error is calculated from the result matrix as the absolute
distance in mm or layers from the simulated source (*) to the peak ΔF (˄). h) Bias is calculated as the
relative position of a peak ΔF(˄) to a simulated source (*) in layers or mm.

Great thanks to coauthors and collaborators: Ishita Agarwal, Quentin Moreau (@quentinmoreau.bsky.social), Bassem Hiba, Sven Bestmann (@armlabucl.bsky.social), Gareth Barnes, and James Bonaiuto (@danclab.bsky.social). It was a huge amount of work and cluster time, but it’s out now!

How do we represent relations between things? And how does it relate to object and action recognition?

Moral of the story? Always check your data. 🔍 Even preprocessed, "clean" datasets can hide unexpected artifacts that mess with your analysis. If you have any good guesses about the origin of this 24 Hz noise, we’d love to hear them!

This also goes to show how superlets are far superior than Morlet wavelets for identifying these phenomenon

Quentin Moreau @quentinmoreau.bsky.social · Feb 21

This isn’t our first rodeo with weird EEG artifacts. 🎢 Sotirios Papadopoulos from our lab also ran into strong, unexpected noise in a shared EEG datasets. Different data, same headache. 🤦‍♂️

1

Quentin Moreau @quentinmoreau.bsky.social · Feb 21

Others? Not so much. 😅 Some subjects needed a bit more tweaking—We had to play around with parameters, rerun iterations, and double-check we weren’t over-cleaning real neural activity. The classic battle: artifact removal vs. preserving the signal.

1

Quentin Moreau @quentinmoreau.bsky.social · Feb 21

To tackle this, we turned to MEEGKIT’s Zapline for noise removal—applying it iteratively to clean up the signal. For some subjects, it worked like a charm! 🎉 The 24 Hz bump was gone, leaving us with cleaner beta activity

Quentin Moreau @quentinmoreau.bsky.social · Feb 21

So, we went back to the raw data thinking maybe the superlets we use for the burst detection spotted something our initial Welch-based PSD analysis didn't. Turns out… every single subject has this 24Hz bump in their PSDs 😑 Which is SLIGHTLY annoying when you're focusing on activity in the beta range

Quentin Moreau @quentinmoreau.bsky.social · Feb 21

This week, we put our beta burst detection algorithm to the test on an open (preprocessed) dataset. Everything seemed fine… until we checked the distribution of the frequency span of the extracted bursts. And there it was—a weird, unexpected 24 Hz peak.⬇️
