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.

Using Quarto to Write a Book I’ve spent the last couple of months revising my Data Visualization book for a second edition that, ideally, will appear some time in the next twelve months. As with the first edition, I’ve posted a c...

Using Quarto to write (and typeset) a book.

We've been saying for a while now that beta bursts might be functionally heterogeneous. Check out @quentinmoreau.bsky.social's paper where we show that different types of bursts have different relationships to behavior in a sensorimotor adaptation task 👇👇👇

I will be at #cosyne2026 next week presenting some new work on "Simultaneous sensorimotor and contextual inference"

Looking forward to seeing many familiar and new faces in Lisbon!

RIP redundancy reduction?

Beautiful work by Liu & colleagues showing that neural redundancy increases with learning, as predicted by a Bayesian model:

A quote by H. Holden Thorp, Editor-in-chief of Science journals, on a black background. The quote is: "… why curtail a program … that cultivates and grows the number of US graduate students and future researchers?"

"There is perhaps no stronger evidence of the [Trump] administration’s objectives to reduce the quality of the US scientific workforce than its treatment of the [NSF]’s flagship Graduate Research Fellowship Program," writes H. Holden Thorp in a new #ScienceEditorial. https://scim.ag/4d0fi3N

Vision Fine‐Tunes Predictions of Bimanual Self‐Touch When we move to touch ourselves, our somatosensory perception is gradually attenuated due to the predictions of the internal forward models about the somatosensory consequences of our movements. Here...

Happy to share that our new paper has been published in the European Journal of Neuroscience (@ejneuroscience.bsky.social)! Using psychophysics, we show that vision fine-tunes self-touch predictions, leading to the temporal modulation of somatosensory perception during movements to self-touch.

How does the brain generalize past experiences without confusing memories? 🧠

Our lab's newest preprint reveals a fundamental division of labor between the cortex and cerebellum that solves this problem. (Check out the cortex-cerebellum video below! 👇) 🧵

The molecular basis of force selectivity by PIEZO2 Nature - PIEZO2 is intrinsically more rigid than PIEZO1, and disparate mechanical stimuli paradoxically evoke opposite conformational and gating responses in each channel.

New paper from the lab led by @ericmulhall.bsky.social addresses how PIEZO1 and PIEZO2 are tuned to different types mechanical forces. From nanometer-scale super-resolution microscopy to in vivo experiments, links single-molecule observations to physiological function.

Later in the movement, global suppression attenuates and surrounding regions (e.g., the forearm) rebound to normal sensitivity.

At the same time, suppression localizes to the expected point of self-touch, reflecting a prediction of the impending contact at the fingertip (kkilteni.bsky.social)

Interesting to think about whether these two effects could be reconciled by effects at two-different scales:

Early in the movement, sensory processing may be globally suppressed in the moved limb (fatatai.bsky.social)....

The extraordinary enigma of ordinary tickle behavior: Why gargalesis still puzzles neuroscience Tickle sensation remains one of the biggest unresolved mysteries in neuroscience—one that scientists are only beginning to unravel.

Why is touch perceived as weaker during movement?

In our new preprint 📝, we examine tactile suppression during reaching.

Using optimal control theory, we show that tactile suppression reflects dynamic, uncertainty-dependent integration of forward model predictions and sensory feedback.

The secret of squeaky basketball shoes When shoes slide across a floor, wave-like deformations of the sole can generate squeaking. The pitch of the squeak depends on the rate at which deformations are generated.

The human body is remarkably adaptable, capable of integrating artificial enhancements from tools to prosthetic limbs.

Researchers have used finger extensions to test how the brain updates its expectations over time.

Why are tactile sensations suppressed during movements? In our new preprint, we explain this as optimal integration of sensory signals with an internal model.
