Excited to see this work published in @natcomms.nature.com! 🧠📊 In-vivo evidence of E/I alterations underlying functional changes in individuals with autism in the large ABIDE1 dataset AND replication in the independent ABIDE2 dataset.

New preprint from stellar IRTG PhD student Amelie Rauland + team on white matter bundle reconstruction! Shows that WM bundles can be reliably extracted from simple 32-direction dMRI & features predict cognition - huge potential for legacy and clinical data. Thread 👇

1/11 Excited to share our @Naturestudy led by @leonooi.bsky.social @csabaorban.bsky.social @shaoshiz.bsky.social

AI performance is known to scale with logarithm of sample size (Kaplan 2020), but in many domains, sample size can be # participants or # measurements...

#ABCD-J #Studienhighlights: Eine kürzlich erschienene Studie zeigt mittels #JTrack Social Unterschiede in Kommunikationsmustern zwischen neurotypischen Erwachsenen und Erwachsenen mit #Autismus-Spektrum-Störung auf. Neugierig geworden? Das ganze Highlight gibt es hier: www.abcd-j.de/de/showcases...
Mehrere Liniendiagramme, die die durchschnittliche tägliche Nutzungsdauer von Smartphones in verschiedenen Kommunikationskategorien zeigen. In Türkis sind jeweils die Daten der Kontrollgruppe mit typischer neurologischer Entwicklung (TD) abgebildet, und in rosa die Daten der Erwachsenen mit  Autismus-Spektrum-Störung (ASD). In der Gesamtkommunikation zeigt sich kein Unterschied zwischen den Gruppen (unterste Grafik). Die TD Gruppe nutzt jedoch mehr verbale Kommunikation als die ASD Gruppe (oberste Grafik), während die ASD Gruppe mehr schriftliche Kommunikation nutzt (zweite Grafik).

🧠⚖️📉 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”

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.

Thanks to everyone's feedback, we have updated our calculator to optimize sample size N & scan time T for fMRI studies: leonoqr.github.io/ORSP_Calcula...

The first new feature is that users can explore how different N & T leads to different accuracy, e.g., N=1000 & T=30min => 81% max accuracy. 🧵

Fully agreed. This adds another layer of complexity

We likely need to differentiate three aspects here
- "True" changes of the trait
- State-changes due to, e.g., sleep
- Measurement error

All three can and will superimpose

In my view, the take-home message is slightly different from the BWAS paper. The latter argued you need large N.

This paper shows that if your target is unreliable, even very large numbers can’t save you

Also, association vs prediction

This is what happens if preprints are treated as „scientific literature“

Don’t get me wrong, I am all for preprinting. But unfortunately, it is often ignored that anybody can preprint anything
