We think of white matter as the highways of the brain. But when we followed development along those highways, we were surprised. The journey is more complex than we thought. My final PhD paper, “Two Axes of White Matter Development”, is now out in @natcomms.nature.com! 🛣️🧠✨

Superb work by the stellar @bsevchik.bsky.social — a new fully processed open data resource focused on exec fxn in psychosis and ADHD.

‼️Also‼️ Brooke is applying to PhD programs now— great time to recruit an absolute star ⭐️ + wonderful human.

The end of a PhD journey 🎓 What a ride - full of lovely people, exciting science, coding tunnels, coffee-brainstorms & amazing conferences! Whole-hearted thank you to all who shared the journey & celebrated with me - especially @sofievalk.bsky.social, @sbe.bsky.social &@mps-cognition.bsky.social 💐🥳❤️

Since July 21st, we have a good reason to celebrate the summa cum laude Defense of the newly minted Dr. Hettwer who received her PhD from @hhu.de under the supervision of Prof. Simon Eickhoff @sbe.bsky.social with strongest support of Dr. Sofie Valk! Congratulations Meike!!!🥂👏🏻🥁🎊

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 ✨

We think of white matter as the brain's highways—uniform conduits between cortices. But what if we study development along tracts? Turns out the journey matters as much as the cortical destination! We're thrilled to share “Two Axes of White Matter Development” www.biorxiv.org/content/10.1...

Are short-term memories just noisier versions of what we perceive? Are they fundamentally different? We (Chaipat Chunharas, @mjwolff.bsky.social, @meikehettwer.bsky.social and myself) delved into this in a paper out now in #elife: elifesciences.org/reviewed-pre.... For a quick summary, a 🧵 below:

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...

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.
