The most recent CBRG preprint on intracortical microstimulation is now available! Over 24 combined years across 5 participants, we delivered 168 million!!! pulses of stimulation and recorded everything that happened.

Intracortical microstimulation in humans: a decade of safety and efficacy
Background Intracortical microstimulation (ICMS) of somatosensory cortex can restore a sense of touch to people with spinal cord injury (SCI). In this early-feasibility clinical trial, we evaluate the...

We had a great time at the @bcisociety.bsky.social meeting in Banff, Canada. We gathered almost all (@hunterschone.bsky.social?) the CBRG attendees (current and former) for the official photo.

Check out @giacomovalle.bsky.social'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.
New in @science.org our study "Tactile edges and motion via patterned microstimulation of the human somatosensory cortex". 🦾 🧠 ⚡

Our new publication in Human Brain Mapping is a roadmap to implanting stimulation electrodes to evoke tactile sensations on the fingers of Brain-Computer Interface (BCI) users. We share the plan and results for 5 study participants across a decade at 2 sites.
