Perilesional neuromodulation replaces lost sensorimotor function in persons with spinal cord injury Nature Biomedical Engineering, Published online: 11 March 2026; doi:10.1038/s41551-026-01627-5Neuromodulation via epidural electrical stimulation both below and above the lesion in three participants with complete spinal cord injury could enable respectively motor activation and sensory perception.

Perilesional neuromodulation replaces lost sensorimotor function in persons with spinal cord injury

will be at #Cosyne2026 presenting this new work on Saturday's posters session starting 1:15p! Come learn about how many seemingly disparate sensorimotor functions in the brain can be explained by a single anatomical motif and computational framework.

We're thrilled to announce the Ctrl-Z Award, a US$2,500 prize for researchers “who discover substantial errors in their published work and take meaningful steps to correct the scientific record."

Cerebellum responds to language like cortical areas One of four language-responsive cerebellar regions may encode meaningful information, much like the cortical language network in the left hemisphere, according to a new study.

Very consistent with @carobellum.bsky.social functional atlas, but providing deeper details. By now the "terra incognita" of the cerebellum isn't so "incognita" anymore!

🧠 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.

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 (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 👇👇👇

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)....

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.
