Paralysed Limbs Reactivated By a Single Brain Cell.

A new breakthrough has been discovered that restores voluntary movement of paralysed muscles. It’s a tiny brain cell and that’s all it takes. Within minutes monkeys learned to harness the power of a single neuron to activate muscles that had been immobilised by drugs. This was learned through experiments aimed at discovering new treatments for paralysis caused by spinal cord injury or stroke.
They’ve discovered there is a surprising degree of flexibility in the kinds of tasks each neuron in the human brain can perform. Our brains contain 100 billion neurons.
“Nearly every neuron we tested could be used to control this type of stimulation,”
said Chet Moritz, lead author and a researcher at the University of Washington
“If a monkey can do it, a human should be able to do it even better”, he said.
It will be a while before this is able to be perfected for use in humans.
