We’re bringing computational psychiatry to #ACNP2026

Our panel shows how RL, DDMs, active inference, and neural models can unpack symptom heterogeneity across anxiety, psychosis, ADHD, depression, and suicide risk-moving beyond diagnoses to mechanisms.

Thank you for the clarification and visualization, that makes sense!

This sounds great - just one clarification question: when you say β€œgroup” level, is this a group of voxels? Or a group of participants? I assume the former because of the spatial dependencies, but I am more familiar with hierarchical approaches in the latter sense, that’s why I am asking.

This is amazing, thank you so much, @layerfmri.bsky.social and team - super helpful, esp. Fig 6&7! After 5 years, I still get puzzled by the way bandwidth and echo spacing/readout time are linked on Siemens. Maybe it’s Philips nostalgia or too much spiral acquisition - where every sample matters ;-)

Und das schließt noch nicht den extra Aufwand ein, alles umzubuchen, die alte Reservierung nach der Reise erstattet zu bekommen, neue Verbindungen nur mit mehr Umstiegen zu finden und so kurzfristig nicht mehr zusammenhÀngende Sitze zu bekommen. Schade!

Liebe @deutschebahn.com,

Dass ihr kurzfristig die #Familienreservierung abschafft, ist enttΓ€uschend fΓΌr unsere 4-kΓΆpfige Familie, die in Kanada immer vom dt. Γ–V schwΓ€rmt.

Dass ihr nun aber 2 unserer reservierten Verbindungen streicht & uns zwingt, neu fΓΌr 35 EUR mehr zu reservieren, ist unredlich

Einspruch gegen die GΓΌltigkeit der Wahl Wir haben den komplizierten Wahlantrag in verstΓ€ndliche Fragen ΓΌbersetzt. Fragen beantworten, Wahlantrag ausdrucken, unterschreiben und abschicken.

So gehen wahrscheinlich Zehntausende Stimmen verloren. Auch meine. Nicht vergessen Einspruch einzulegen: www.auslandswahl.de/einspruch
