I am happy to bring your attention to an upcoming workshop I am co-organising on early social experience, neuropsychological development, and mental health. This will be held in Sicily on September 2nd-5th 2026: centromajorana.it/earlydevelop...

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

An accessible overview on why beta band activity is best seen as a diverse set of events and not an oscillation, along with cortico-subcortical network responsible for specific waveform shape. @hollyrayson.bsky.social @quentinmoreau.bsky.social Solène Gailhard @danclab.bsky.social

Beta Burst Waveform Diversity: A Window onto Cortical Computation - Holly Rayson, Quentin Moreau, Solene Gailhard, Maciej J. Szul, James J. Bonaiuto, 2025
Neural activity in the beta band is increasingly recognized to occur not as sustained oscillations but as transient burst-like events. These beta bursts are div...

🚨🚨🚨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.

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! 🧠📈

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

The second paper of my PhD is now out in the world! It is a longitudinal study exploring if intolerance of uncertainty predicts generalised anxiety. Thanks to @profhelendodd.bsky.social, @jmorriss.bsky.social, @hollyrayson.bsky.social for all your support doi.org/10.1016/j.janxdis.2025.103004

Check out our new preprint! It's especially useful for looking at rhythmicity in infant EEG signals 🧠👶
