Our goal is to understand the neural computations used by the brain to construct and update internal models of the body Donders Institute, Radboud University, Nijmegen, NL PI: @lukemillerneuro.bsky.social
As body-augmenting technologies become more common, it is important to understand how the brain decides what counts as "the body", and how that changes over time.
My first postdoc paper 🦾 now out in @elife.bsky.social 👇
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.

How does the brain adapt to artificial body extensions over time?
With a wearable finger-extension device, we reveal distinct phases of proprioceptive plasticity: during wear, after active use, and even after removal.

Congratulations to @pevianiv.bsky.social on the BRNet ECR Pioneer Award 🏆🎉
It has been a pleasure working with Valeria in our lab. A fantastic and well-deserved recognition 👏
🎉 BRNet ECR Pioneer Award winner 🎉
Congrats to Dr Valeria Peviani 🏆
A postdoc at the Donders Institute & UKE Hamburg, Valeria’s work explores how body perception emerged from multisensory signals, combining computational modelling, psychophysics & electrophysiology.
👏 Well deserved!
New paper led by @pevianiv.bsky.social!
Using EEG and varied hand positions, we tested how the brain localizes touch. Neural gradients showed limb-specific, intrinsic coding emerging ~160 ms after touch, challenging extrinsic remapping theories.

Really happy to share that my talk on how spatial finger augmentation reshapes proprioceptive and tactile maps was accepted as an oral presentation at @ncmsociety.bsky.social meeting in Kobe 🇯🇵 I will present a computational framework for how artificial extensions integrate into body representation.
If you're at #IMRF2025 @imrf.bsky.social and interested in chatting about our newest line of work on body augmentations that we developed at the @bbt-lab.bsky.social, feel free to reach out! Always happy to connect. We have a preprint here: www.biorxiv.org/content/10.1... 🦾
Congratulations to @pevianiv.bsky.social for an amazing talk! Don't forget to check out her latest preprint 👉 www.biorxiv.org/content/10.1...

Just in time for #BRNet2025 !
New work from the lab on how the body representation dynamically adapts to wearable augmentation 🦾
How does the brain integrate artificial body extensions? Using a custom-built finger-extending exoskeleton, we show that wearable augmentations are quickly integrated into body representation, with proprioceptive space adapting to the device’s structure and function.

Great first keynote talk at #BRNet2025 by Pieter Medendorp @pmedendorp.bsky.social, featuring work of @pevianiv.bsky.social:
@pevianiv.bsky.social talking about her excellent work on biases in hand perception as an example of the use of computational modelling in body representation research. Paper here: www.cell.com/current-biol....
And now the second part on model fitting!
@pevianiv.bsky.social
Welcome everyone to the first day of the #BRNet2025 Conference in Utrecht! 🇳🇱
We have just finished the first part of the computational modelling workshop, led by @lukemillerneuro.bsky.social @pevianiv.bsky.social @kkilteni.bsky.social. A lot of important knowledge, great questions and discussions!
New preprint!
We find that tactile remapping relies on intrinsic, limb-specific spatial codes, emerging ~160 ms post-stimulus in centro-parietal regions.

New preprint!
Adolescents with Restrictive Eating Disorder show greater biases in abdomen localization. Hand perception biases were similar across groups, with no tactile acuity differences, suggesting early, body-part-specific distortions.
