- Reposted by Christoph BledowskiMy first TEDx talk just came out. It's always fun to talk about your own research area to the general audience, and its even more fun when you are lucky enough to be supported by such a platform. Happy to hear your thoughts :-) youtu.be/UyUclyHx8d8?...
- Reposted by Christoph BledowskiGreat work by Roni Tibon (not on BlueSky) - surprising that negligible difference in fMRI correlates of semantic vs episodic retrieval?
- Are episodic and semantic memory really that different? Using closely matched tasks, a new study found no substantial neural differences between recalling personal experiences and general knowledge: www.nature.com/articles/s41...

- Reposted by Christoph BledowskiOver the years, I have written a few Jupyter/Rmd/Matlab notebooks that attempt to teach some statistical concepts, particularly in neuroimaging. You can find them here: www.mrc-cbu.cam.ac.uk/people/rik.h..., though I will say a bit more about each one in a number of posts over next few days.
- Reposted by Christoph BledowskiIt won't actually exist for another month or so, but because it now 'exists' on amazon, I'll humbly observe that, after working through this book, your student/trainee would be able to read and understand all but two or three papers in this week's J. Neurosci. Check it out:

Using 500k+ behavioral trials, we show that #serialdependence deviates from #Bayesian predictions, pointing to a new narrative about how recent experience shapes perception. @aozkirli.bsky.social @achetverikov.bsky.social

- Reposted by Christoph Bledowskinew paper in TICS officially out today. great learning from and writing with Anastasia, and super cool cover art from Prof. Pinar Yoldas. www.cell.com/trends/cogni...
- Reposted by Christoph BledowskiReally excited to see this preprint out! Fernanda did an amazing job at demonstrating how you can accurately predict retinotopy from T1w scans alone. This is important for several reasons: 1/4
- Investigating individual-specific topographic organization has traditionally been a resource-intensive and time-consuming process. But what if we could map visual cortex organization in thousands of brains? Here we offer the community with a toolbox that can do just that! tinyurl.com/deepretinotopy

- Reposted by Christoph BledowskiNow out in #ScienceAdvances: @baiweiliu.bsky.social and I ask how internal (goal) and external (sensory) selection are coordinated during visual search. The key insight: internal and external selection are not inherently serial, but may develop in parallel in the human brain: doi.org/10.1126/scia...

- Reposted by Christoph BledowskiAny early-career researchers in #workingmemory wanting to contribute to an #openscience initiative? I'm looking for help building up a data hub resource for the field. Volunteers can expect to devote a few hours, and might pick up insights into handling research data and how to use Github.
- Reposted by Christoph Bledowski📣 Out in TINS (@cp-trendsneuro.bsky.social): Neural processing is often described as either externally or internally directed. In our new Forum article, we (@freekvanede.bsky.social & Kia Nobre) propose a multilevel framework for conceptualising external and internal continua of brain processes.

(How) are these empirical phenomena related? Check it out in the latest work led by @baiweiliu.bsky.social: doi.org/10.1371/jour...

- Reposted by Christoph BledowskiWho doesn't like a good model of the brain? Yet, from simple regression to neural nets, some limitations keep popping up (e.g., overfitting) @mjwolff.bsky.social & I saw some cool but puzzling data, ran a quick analysis & found one such limitation: model mimicry. Now in #naturecommunications &🧵below
