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. Now in @elife.bsky.social: elifesciences.org/reviewed-pre...

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. www.jneurosci.org/content/46/5...

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... 🦾

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. www.biorxiv.org/content/10.1...

New preprint! We find that tactile remapping relies on intrinsic, limb-specific spatial codes, emerging ~160 ms post-stimulus in centro-parietal regions. by @pevianiv.bsky.social, Hüseyin O. Elmas, @pmedendorp.bsky.social‬, & @lukemillerneuro.bsky.social www.biorxiv.org/content/10.1...

Feedback control undistorts body representations: A possible solution to the hand paradox doi.org/10.31234/osf... 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

My lab’s first attempt at characterizing reference frame transformations during tool-extended sensing. Very happy to see this out! #neuroskyence #psychscisky #sensorimotor

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. www.biorxiv.org/content/10.1... @lukemillerneuro.bsky.social @pmedendorp.bsky.social

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).

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 Link: www.ru.nl/en/working-a...

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

Dear future reviewers of my manuscript, I am terribly sorry that the figures are placed at random places within the page. It was not my decision to split a paragraph in two with a figure. It was the stupid docx-to-pdf conversion process required by the journal. Don't hate me!
