congrats！Valerie

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 ⭐ 🌈 🧠 🚀

woooowoooo

🎉🎉#OHBM2025 is just around the corner! Remember to visit the SP-SIG stall next to the registration desk and add stickers to your badge describing your research interests!

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!

Congrats bro!

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.

🧠⚖️📉 How does the cortical excitation-inhibition ratio mature during adolescence?
We asked this in our new paper just out in #ScienceAdvances ✨

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.

🚨🚨🚨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!

1) The heritability was robust across samples of different ages
2) GWAS identified 16 genes, involved in metabolic process
3) The genes were further validated using Allen Brain
4) Individual protective and risk metabolic makers showed reversed correlations
5) SCZ, PTSD, and BP won the game

The architecture of the human default mode network explored through cytoarchitecture, wiring and signal flow - Nature Neuroscience The default mode network (DMN) is implicated in cognition and behavior. Here, the authors show that the DMN is cytoarchitecturally heterogeneous, it contains regions receptive to input from the sensory cortex and a core relatively insulated from environmental input, and it uniquely balances its output across sensory hierarchies.

Brains minimize energy consumption while maximizing computation. In humans, this trade-off is reconciled towards complex behaviors & hence relatively high energy use
