- Reposted by Jan HaakerComparing registrations to published papers is essential to research integrity - and almost no one does it routinely because it's slow, messy, and time-demanding. RegCheck was built to help make this process easier. Today, we launch RegCheck V2. 🧵 regcheck.app

- Reposted by Jan HaakerThis paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!
- Would love to hear expert views on this paper. It appears to show that the operationalization of brain activity the field has relied on for 3 decades—the BOLD response—is not actually a sensible measure of brain activity. www.nature.com/articles/s41...
- Reposted by Jan HaakerfMRI signals “up,” but neural metabolism might be going “down.” In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes. rdcu.be/eUPO8 funds @erc.europa.eu #neuroskyence 🧵:

- Reposted by Jan HaakerThe party drug MDMA (“ecstasy”) shows promising efficacy as adjunct to psychotherapy. The psychostimulant with entactogenic properties is known to induce arousal and euphoria. We now studied the neurochemistry underlying the behavioral effects of MDMA in rats lacking serotonin in the brain.
- So cool to be included in this project showing that overgeneralization of threat responses learned by observation predicted higher anxiety symptoms in adolescents during wartime. All the credits go to Yoni Fishman and Tomer Shechner's Team doi.org/10.1016/j.br...

- Reposted by Jan Haaker👏 Congratulations to @uni-hamburg.de for being rated Germanys most sustainable university. Glad to see that UHH has been committed to lead by example in this important area over the past years. www.uni-hamburg.de/en/newsroom/...
- Reposted by Jan HaakerExcited to share that the main work of my PhD has been published! We found that having control over pain makes expectations more precise, and changes pain perception. This is accompanied by activation changes in the PAG, SMA and ACC. You can read the full version of the paper here: rdcu.be/eQy6X
- Reposted by Jan HaakerWe also have some new affiliated projects! 🤩 First, we heard a great talk from @jlaferton.bsky.social on enhancing treatment expectations for knee replacement outcomes🦵😷 Then, Marcel Wilhelm and Gertraud Gradl-Dietsch presented a project on the impact of different treatment framing on depression ☹️
- Reposted by Jan HaakerLast up is @christianbuchel.bsky.social telling us about all things wrong with our current publishing system and how new models (for example @elife.bsky.social) are trying to break these barriers! 💪 Of course featuring this gem of a video by @glaucomflecken.bsky.social: youtu.be/ukAkG6c_N4M?...

- Reposted by Jan Haaker📢 Thrilled to share our paper is out now in @natcomms.nature.com Shared computations underlie how we acquire actions that are mutually beneficial, instrumentally harmful (benefits self at the expense of others), altruistic (benefit others at the expense of self), or mutually costly 🧵 rdcu.be/eL8mZ
- Can we learn about unpredictable threats via observation of others? Yes, temporally predictable and unpredictable threats are learned by distinct contributions of the amygdala and hippocampus. ALSO: We find higher activation in the amygdala and anterior insula to others' pain that serves learning.
- Excited to try this! The waiting list makes me even more curious
- Reposted by Jan HaakerOur new @frontiersin.bsky.social article focused on how learning strategies and #open-label-placebos (OLPs) can affect academic performance. This study tested a subgroup and explored if e.g. learning strategies could impact the influence OLPs hold on cognitive outcomes. What did we find? ⤵️
- Reposted by Jan Haaker1st Sharp Lab preprint! 🚨 We tested how anxiety affects task generalization—not how people generalize threat stimuli, but how they reuse action-outcome structures when planning in new contexts. Worry makes people avoid reusing actions that co-occurred w/ threat! 📄: osf.io/preprints/ps... 🧵 1/12
