The Cortical Bionics Research Group seeks to build next-generation intracortical Brain-Computer Interfaces that enable dexterous control of bionic hands.

Check out @giacomo_valle's summary of our new paper showing the details that we can convey to BCI users through spatio-temporally patterned stimulation in somatosensory cortex. This is a great step towards restoring natural sensation from future prosthetic hands.
1/ New in @ScienceMagazine our study "Tactile edges and motion via patterned microstimulation of the human somatosensory cortex". 🦾 🧠 ⚡ https://t.co/eg3WOID4ol Interesting related perspective by prof. Paul Marasco https://t.co/Ci0JC3Yadu

Marc Schieber has published his insightful thoughts on the below paper and where it fits in the broader efforts towards dexterous neuroprosthetic hands in Nature BME: https://t.co/Out2xdGAh3
Our group has a new paper out now in Nature BME, led by Charles Greenspon. It covers a number of updates on how we can restore tactile sensation from the hand using intracortical microstimulation (ICMS).

Tune in at 11:00 CT today to learn more about our work restoring sensation through electrical stimulation in the cortex.
Pushing the Limits of ICMS for Tactile Feedback with UC Chicago scientist, Dr. Charles Greenspon, is tomorrow (online). Make sure you register today, it's not a conversation you want to miss. 🔗 https://t.co/N7VB3ETIOr

This was a big team effort by the labs, and especially the study participants, across three universities (@UChicago, @UPMC, and @cwru). These results are a big step forward for using ICMS to restore tactile sensations post-injury. https://t.co/GMSFnFzRo2

These interactions allowed us to improve the ability of participants to both locate which finger an object was contacting as well as how much force was being applied to it.

Given that some electrodes overlapped, we examined the interaction and found that they generally summed together making more intense sensations.

We compared the percept locations with receptive field locations (area on the hand that when touched evokes neural activity near an electrode) when possible and found that the vast majority of percepts fell within the matched receptive fields.

We first looked to see if ICMS-evoked percepts (a sensation caused by stimulation on an electrode) were in consistent locations across the duration of the study and found that across 2-7 years they were.
