Researchers present a new theory which states, following amputation, the neural circuitry connected to the missing limb becomes entangled with other neural networks, specifically ones responsible for pain perception.
Researchers have developed a new electronic skin that can allow amputees to perceive touch sensations via their prosthesis. The technology, dubbed e-dermis, can recreate the sense of touch and pain by sensing stimuli and relaying impulses back to peripheral nerves.
Researchers report amputees are able to control a robotic arm with help of brain implants and BMI technology. The study details how brain areas that control both the intact arm and amputated limb can create new connections and learn to control the robotic arm, even years following the loss of a limb.
Following targeted motor and sensory reinnervation, a procedure that reroutes residual limb nerves to intact muscles and skin in amputees, the brain remaps both motor and sensory pathways. Additionally, researchers note, TMSR may help counteract poorly adapted cortical plasticity following amputation.
