TMR going far

And last one for tonight, Natalia pointed out that Dr. Kuiken's work in Chicago has been in the news again, thanks to some advancements that led to a J Neurophys paper. You'll remember the work (targeted muscle reinnervation) from the big media blitz a couple years ago.

Long story short, they reroute nerves that were going to an amputated limb, to muscles on the chest, side, and abdomen. Patients think about moving the non-existent limb, causing the fibers to fire, thereby eliciting a EMG detectable twitch of the new target muscle. That activity is then translated into movement of a robotic arm. The new paper discusses nerve targets, and more electrodes, making movement detection 95% accurate for 16 movements.

Paper found here.
