Neuron-controlled Prosthetic Hand Operated by a Monkey

China's Zhejiang University rolled out a cortical neuron-controlled prosthetic hand. A monkey named Jianhui can operate the mechanical prosthetic hand by its mind to grab food and drink to feed itself.

A micro-miniature sensor was implanted into Jianhui's brain by minimally invasive procedure to obtain its brain electrophysiological activities. The pattern extracted from the activities is decoded to determine what Jianhui is thinking about: change palm position/orientation, pinch grip, palm grip, hook grip, finger adduction or finger point. Thus the prosthetic hand can implement the attempted actions.

This brain-machine interface (BMI) technology research is funded by a rehabilitation project aiming to help disabled people suffering from paralyzing condition or amputee. Potentially BMI-based technologies can enable these disabled people to feed themselves and control their wheelchairs
