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!

The Spatial Coding of Touch Is Defined in Intrinsic, Limb-Specific Coordinates: An EEG Study The brain computes the spatiotopic position of touch by integrating tactile and proprioceptive signals (i.e., tactile remapping). While it is often assumed that the spatiotopic touch location is mappe...

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...

Valeria C. Peviani @pevianiv.bsky.social presenting her talk "A mirror symmetric spatial code maps touch on both hands in the human brain".

Floris van Wettum presenting his poster "Optimal integration of a novel sound-to-space mapping into sensorimotor control loops".

Huseyin Orkun Elmas presenting his poster "Bayesian modeling reveals distinct priors for tactile and proprioceptive localization".

New work from the lab on how the body representation dynamically adapts to wearable augmentation 🦾

Dynamics of sensorimotor plasticity during exoskeletal finger augmentation How does the brain integrate artificial body extensions into its somatosensory representation? While prior work has shown that tool use alters body representation, little is known about how artificial...

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!

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!

The spatial coding of touch is defined in intrinsic, limb-specific coordinates: an EEG study The brain localizes touch in space by integrating tactile and proprioceptive signals, a process known as tactile remapping. While it is often assumed that the remapped touch is encoded in an extrinsic...

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.
