New, expanded preprint! Sensorimotor training makes a finger-extending exoskeleton feel lighter, suggesting active use helps wearable augmentation become perceptually transparent. Much longer, much better version now on bioRxiv: w/ Arina Schippers @mattlongo.bsky.social @lukemillerneuro.bsky.social

Lovely to see our eLife study in BPS Research Digest @bpsofficial.bsky.social @researchdigest.bsky.social! We studied how the brain adapts to finger extensions, finding three rapid phases of sensorimotor plasticity as users integrated them into body representation. www.bps.org.uk/research-dig...

Throwback to the poster session at #BRNet2026, where our PhD students presented their fantastic work! Each poster deserves its own spotlight; we will be sharing them in the thread below 👇

Huge congratulations to Valeria Peviani on winning the Early Career Researcher Award from @bodyrepnetwork.bsky.social! 🎉 It is wonderful to see her creativity, brilliance, and impact recognized by the community. We are so proud! Congratulations, @pevianiv.bsky.social!

Just in time for #NCMKobe26, our preprint: www.biorxiv.org/content/10.6.... Attaching an exoskeleton leads to rapid perceptual integration; ~20 min of training makes it feel even lighter. See supplement for model details! w/ Arina Schippers @mattlongo.bsky.social @lukemillerneuro.bsky.social 🦾🧠

Excited to be in Kobe for the Neural Control of Movement conference! 🇯🇵🧠 #NCMKobe26 @ncmsociety.bsky.social I will be presenting Friday at 10:30 on how finger-extending exoskeletons are integrated into the human sensorimotor system. Very grateful to be here as an NCM scholarship awardee!

Great time at the Donders Institute Open Day – De Brein Show! 🧠✨ We brought our Exoskeleton demo, where visitors experienced extending the body with extra long fingers. Thanks to everyone who stopped by, and our team: Floris van Wettum, Eleni Manias, Thomas Kooiman, and Chris Vajdík 🦾

New paper led by @pevianiv.bsky.social! We show maps of a hand-held tool can be built with accuracy comparable to arm. Tool use did not change accuracy but affected precision. This suggests the sensorimotor system can extend body-like representations to tools. www.sciencedirect.com/science/arti...

Curious how YOUR brain adapts to body augmentations? 🧠 On 21 March we will be at the Donders Institute Open Day (De Brein Show) in Nijmegen. Our lab @bbt-lab.bsky.social will be part of the demos, where you can try our finger-extending exoskeleton 🦾 More info 👉 www.ru.nl/donders-inst...

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. 🔗 buff.ly/HxxCzTz

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 👏

🎉 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. www.jneurosci.org/content/46/5...

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...

Throwback to the poster sessions at #BRNet2025 where our brilliant master’s and PhD students from the Brain, Body, and Technology Lab presented their fantastic work! Each of their posters deserves its own spotlight; we’ll be sharing them in the thread below 👇

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

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....

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. by @pevianiv.bsky.social, Hüseyin O. Elmas, @pmedendorp.bsky.social‬, & @lukemillerneuro.bsky.social www.biorxiv.org/content/10.1...

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. Led by @pevianiv.bsky.social osf.io/preprints/ps...

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

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
