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 👏
So well deserved! Congrats @pevianiv.bsky.social on this accomplishment!
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.
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.

Amazing work! Congrats all
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... 🦾
It was great having you there, Micah! Looking forward to seeing you at future BRNet meetings
New work from the lab on how the body representation dynamically adapts to wearable augmentation 🦾
Just in time for #BRNet2025 !
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.

New preprint!
We find that tactile remapping relies on intrinsic, limb-specific spatial codes, emerging ~160 ms post-stimulus in centro-parietal regions.

Feedback control undistorts body representations: A possible solution to the hand paradox

New theory paper with @pevianiv.bsky.social where we take a stab at reconciling the seemingly contradictory findings of distorted body representations & optimal motor control

Good question! And short answer is that I don’t know. But I’m sure how we formalized the transformations in the paper is an oversimplification. Lots more to do! I added your paper linked in the OP to my reading list. Perhaps the answer is there!
My lab’s first attempt at characterizing reference frame transformations during tool-extended sensing. Very happy to see this out!

For anyone interested you in updates on the exciting research coming out of my lab, you can follow us here!
Humans project tactile sensations from a tool into space, as if part of the body. How? We show tactile feedback is projected into gaze-centered coordinates, offering a framework for tool-based sensory projection.

After 16 hours on the Stockholm-Berlin train, arrived just in time for #MindBrainBody!
Excited to present our poster on "The influence of finger-extending exoskeletons on tactile and proprioceptive localization" during Poster Session D (16:10-16:55, D06).
Psychologists and neuroscientists are calling for international pressure towards immediate ceasefire in Israel, Palestine & Lebanon, respect for international humanitarian law, end of the occupation, and release of all hostages.

New open PhD position in my lab at the Donders Institute!
We are looking for a motivated PhD candidate with an interest in the computational underpinnings of body augmentation and embodiment.
Deadline: 14 February, 2024

Our attempt to resolve/dissolve the so-called “hand paradox”! This has been a labor of love for Valeria and I’m so happy to see it out!
Our research challenges the long-held idea of distorted hand model!
With @lukemillerneuro.bsky.social and Pieter Medendorp we show that biases in finger perception arise from the Bayesian integration of accurate but noisy signals on finger geometry. Check out the preprint: bit.ly/46LOrSA
NEW PAPER ALERT!
The latest in our series of studies on the sensory embodiment of tools
A Somatosensory Computation That Unifies Limbs and Tools eneuro.org/content/10/1...
We find that localising touch on a tool repurposes *the same computation* used to localise touch on the body
