How does the cerebellum contribute to cognitive functions? The role of the cerebellum in motor functions is well understood. But why is the same circuitry engaged in functions such as working memory, language, and social cognition? This Unsolved Mystery looks...

Also out today - A quick intro piece on the role of the cerebellum in cognition. What does it do? How will we find out? This is what @actlab.bsky.social and I think the critical questions are right now. It was fun to write - especially the section on evolution....

Repeated Viewing of a Film Clip Changes Event Timescales in The Brain Many everyday experiences share a recurring structure: routines, familiar routes, rewatched films, and replayed songs. How do repeated encounters with such structure alter the brain’s representations ...

How do the brain’s event representations change as we gain familiarity with an experience?

Brain regions’ representations can become coarser or finer as events become familiar. Slow-timescale structure predicts memory.

Public communication alters private confidence Andreassen et al. demonstrate that confidence exhibited in public affects our private assessment of confidence.

How does uncertainty transmit from one head to another? Our new paper out today in @currentbiology.bsky.social reveals how public communication alters private confidence.

My course on consciousness is now online: six 90´ lectures featuring both history and recent experimental results on ignition, P3b, working memory, neural manifolds… unpublished results too.

Integrating behavioural experimental findings into dynamical models to inform social change interventions Nature Human Behaviour, Published online: 16 March 2026; doi:10.1038/s41562-026-02417-4Tănase et al. show how integrating discrete-choice modelling into the complex contagion theory reveals individual differences in adoption of innovations and informs social network interventions.

Neural Tuning for Ordinal Processing: Convergent Patterns in Human Brains and Artificial Networks Processing ordinality, i.e., the rank of an item in a series such as 1st, 2nd, 3rd, etc., is a fundamental skill shared by humans and animals. While humans often use symbolic sequences like numbers or...

Neural geometry in the human hippocampus enables generalization across spatial position and gaze Hippocampal neurons track positions of self, others, and gaze direction. However, it is unclear how their respective neural codes differ enough to avoid confusion while allowing for abstraction. We re...

🧠 Resting-state fMRI is often treated as the gold standard for studying the brain’s intrinsic organization.

But is it actually the best way to estimate functional architecture?

We tested this directly.

Every time you experience something new, your brain faces a decision: Should it update an existing memory or create a new one?

In our new paper in @sfnjournals.bsky.social #JNeurosci, we isolate that exact decision, moment-by-moment during learning 🧵

Bilingual language processing relies on shared semantic representations that are modulated by each language www.pnas.org/doi/full/10.... fMRI with participants reading hours of natural narratives in their native & non-native languages then compared semantic representations between the two languages

Inverted encoding of neural responses to AV stimuli reveals super-additive multisensory enhancement elifesciences.org/articles/97230 What's the deal with EEG based AV super &/or sub-additive effects? Do standard univariate analyses simply obscure multisensory interactions? Enter inverted encoding 😲

I’ve started referring to the idea of LLM agents that can magically build complete working software applications from vague human specifications as “Full-self-coding”.

I think it’s on the same time horizon as Full-self-driving. I.e. likely never.
