It's a wrap! BIG thanks to all speakers, chairs, attendees, and our organizing committee - particularly our superstar local organizers Johan and Saurabh - for making our gradient dreams come true for the sixth year in a row ⭐ 🌈 🧠 🚀

I finally defended my thesis! Thanks all! I started my PhD during covid! I am really grateful that my supervisor @sofievalk.bsky.social picked me to be her first PhD student when I was naive to neuroimage. I have been so lucky to stay in this happy and respectful academic environment so far!

🧠⚖️📉 How does the cortical excitation-inhibition ratio mature during adolescence? We asked this in our new paper just out in #ScienceAdvances ✨ “Adolescent maturation of cortical excitation-inhibition ratio based on individualized biophysical network modeling” 📄 www.science.org/doi/full/10.... 🧵⤵️

Adolescent maturation of cortical excitation-inhibition ratio based on individualized biophysical network modeling

Individualized simulations reveal a decrease in excitation-inhibition ratio in association areas throughout adolescence.

🚨🚨🚨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.

Happy to share my last PhD work "Genetic, transcriptomic, metabolic, and neuropsychiatric underpinnings of cortical functional gradients". We used UKB, HCP, and QTAB to analyze the genetics of functional gradients. The results are so good, consistent, and inspiring! (1/3)

Thrilled to share my latest work "Microstructural asymmetry in the human cortex" now out in NatComms. www.nature.com/articles/s41... This work used cytoarchitecture (BigBrain), T1w/T2w, qT1, and MT measures to bring the cortical asymmetry from macrostructure to microstructure.

Microstructural asymmetry in the human cortex - Nature Communications

The human cortex displays an anterior-to-posterior asymmetry, identified via both post-mortem and in vivo microstructural measurements. Microstructural asymmetry is heritable, varies across cortical l...
