Brain Signals from One Primate Move Paralyzed Limbs in Another Primate
Researchers from Cornell’s School of Electrical and Computer Engineering and Harvard Medical School’s Department of Neurosurgery have developed a new neural prosthetic that uses neural activity recorded from premotor neurons to control limb movements in functionally paralyzed primates. This is a step toward making brain-machine interfaces for paralyzed humans to control their own limbs using just their brain activity. Previous research has been limited to controlling external devices such as robotic limbs.
Behold – our recent ancestor, the gorilla, and ourselves, the human:
There are many characteristics that separate us from our monkey fathers. Most notably, factors that mark the evolution are the use of fire, use of tools, and a bigger brain. A recent study suggests that it is actually the onset of the use of fire that explains the ability to begin to grow a larger brain. According to a timeline of human history, the earliest Homo Sapiens appeared shortly after beginning to use fire to cook food:
