What happens to the brain’s body map when a body-part is removed?

Scanning patients before and up to 5 yrs after arm amputation, we discovered the brain’s body map is strikingly preserved despite amputation

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.

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.

Can the motor system use sensory expectations to prepare for unexpected events?

Excited to share my latest work with @andpru.bsky.social – where we establish that sensory expectations shape neural population dynamics in motor circuits!
