I am even warier than the authors about the broad-brush applications of the QRP label. However, I stand firmly against classifying data dredging/fishing expeditions as responsible research practice and as exploratory research. Science reform has distorted our understanding of scientific exploration.
P-hacking vs Exploratory Analyses

"Reanalyzing data through multiple methods in search of statistically significant results (i.e., p-hacking) is questionable only if concealed; when justified and transparently reported (e.g., exploratory studies), it reflects responsible practice."

Great work by Roni Tibon (not on BlueSky) - surprising that negligible difference in fMRI correlates of semantic vs episodic retrieval?

Finally: the fantastic #registeredreport from bsky-less Roni Tibon is out: www.nature.com/articles/s41... showing less difference between #episodic vs. #semantic #memory than one might have thought.

Proud to have contributed a tiny part to this great paper.

Personally, I am sure animals have a cognitive map.

Whether that map is topographical, can, and is used to compute novel shortcuts is another question though.

Here, we simply argue that Tolman's sunburst maze results are not well replicated and the apparatus is not a good test of this question.

Can humans & animals really use internal maps to take shortcuts?

Tolman famously said yes - based largely on his Sunburst maze.

Our new review & meta-analysis suggests evidence is far weaker than you might think.

In 1946, Tolman et al. reported that rats could take a novel shortcut to a goal after training on an indirect route, supporting the Cognitive Map theory. However, a review of subsequent Sunburst maze...

With some trepidation, I'm putting this out into the world:

It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.

My hope is that this will be a living document, continuously improved as I get feedback.

With the end of 2025, my short stint on #xiaohongshu comes to an end after the second honestly completely innocuous video was presumably shadow banned or broken so it could not be shared. That's a bit too silly for me.

In this sense "Guten Rutsch" to everyone. Let's hope 2026 will be less of a catastrophe. Enjoy the small good things with people you love.

Before going back to Germany for Christmas, we took our bikes for another spin around Lake #Taihu in #Suzhou. The condition were simply superb: Not many people, clear weather, temperatures around 10 to 15 C, amazing cycling infrastructure and stunning scenery.

fMRI 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.

Doing non-causal inference (and being explicit about it), yet using a causal word as second word in the title.

If you pay Nature € 10.690, they will publish this in Nature Ageing.

I can tell you what I think of that for free.
