Wer Leute dazu zwingen möchte, für €1,20 pro Stunde zu arbeiten, ist kein guter Mensch und sollte keine politische Verantwortung tragen dürfen. Solche sklavenartigen Ausbeutungsverhältnisse sind nur eines: Ein klares Zeichen, dass wir systematisch etwas ändern müssen. Leben in Würde für alle!
Und so kommt die Arbeitspflicht schleichend. Erst für Asylsuchende, dann für unter 25-Jährige – erst nur in Thüringen und als Nächstes wo und für wen?

🚴‍♂️ Guten Morgen, HHU! Team HHU & UKD in den Top 5 beim Stadtradeln:
Beim diesjährigen Stadtradeln haben wir als gemeinsames Team mit dem UKD 34.195 km zurückgelegt und 5,6 Tonnen CO2 eingespart. 1/3

Britta Haßelmann zeigt hier auf, was in der Union gerade
grundlegend schiefläuft.

Oder: Wie die CDU sich diese Woche wieder selbst ein Bein gestellt und der AfD alle Trümpfe in die Hand gespielt hat.

Out now as a preprint!

We investigated the effect of outcome-uncertainty on learning and endogenous pain modulation in a probabilistic gambling task.

Results show that pain inhibition from winning pain relief increases as a function of certainty in what action lead to the relief of pain.
Reward-induced endogenous pain inhibition scales with action-outcome certainty in humans https://www.biorxiv.org/content/10.1101/2025.10.31.685818v1

Wenn Söder von "linker Kampagne" spricht, versucht er das eigene Klientel zur Ordnung zu rufen um sich bedingungslos hinter den rassistischen Äußerungen zu stellen, so hat der Sozialflügel der Union auch schon kurz aufgemuckt.

Wenn Antirassmus links ist, wissen wir ja jetzt alle wo sie stehen.

Dass wir im heutigen Stadtbild so viele Stolpersteine haben, liegt übrigens daran, dass sich mal eine Regierung an bestimmten Menschen im deutschen Stadtbild störte.

it's wild that R, the ubiquitous statistical computing language, was co-created by a Māori prof (Ross Ihaka) — and yet the vast majority of scientists who use R don't know

this is like inventing the toaster. possibly the largest impact of a single member of an indigenous community on modern science

Kohl et al. report that sensorimotor network dynamics can distinguish patients with Parkinson’s disease from controls and highlight the importance of network context of motor cortical activations.

New paper out doi.org/10.1093/brai...!

We show that sensorimotor network dynamics are altered in Parkinson’s disease and highlight the importance of looking at motor cortical activity within the broader brain network context to better understand pathophysiological changes underlying PD.

Really glad that my first paper is now out in @painthejournal.bsky.social 😁🧠!
Hubschmid et al. find that monetary rewards increase sensory signal strength leading to enhanced pain discrimination. Mechanistically, this process seems to be driven by learning from positive prediction errors. Learn more in #PAIN bit.ly/4lWzNjb

I’m sure you’ve always wondered how reliable Granger causality of source reconstructed MEG really is. Better yet, you surely wonder how to improve it. You’re in luck, I’ve just arrived at @meguki2025.bsky.social to discuss it. All jokes aside, meet me at poster 38 if you’re interested. 👋🏼🧠

Just arrived at @meguki2025.bsky.social excited to present results on head movement reduction in people with Parkinson‘s using individual head casts. Additionally we can replicate prior findings on laminar source reconstruction! If you want to find out more, do not hesitate to find me at poster 45!

🚨🚨🚨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!
