As seen in the trial, when the vagus nerve receives extra stimulation, it causes the brain to release neuromodulators, which regulate the body’s responses.
Up until this point, researchers have succeeded in giving amputees control over robotic hands by measuring nerve activity in the residual limb.“Patients get this big ball of nerves called a neuroma,” says University of Michigan plastic surgeon Paul Cederna, who co-developed this new system.
Most work on 3D bio-printing is done in culture dishes, but this experiment was unique in that the team was able to do this in laboratory rats, and because the lab-grown cells then successfully bridged the gap of a cut spinal cord and partially restored movement to the animal's hind quarters.
Inject RTX, as it’s known, into an aching joint, and it’ll actually destroy the nerve endings that signal pain. That’s toxic, leading to the inactivation of the pain-sensing nerve endings.This leaves other varieties of sensory neurons unaffected, because RTX is highly specific to TRPV1.
