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

Dominika Radziun @nikaradziun.bsky.social · Jul 4

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.

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...

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!

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.

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).

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
