In the calcium channel there are four so-called voltage sensors that detect electrical nerve impulses.

"The spinal cord is like a highway, carrying information in the form of nerve impulses to and from the brain," said Professor George Malliaras from the Department of Engineering, who co-led the research.

They are also used to study nerve impulses in muscles, as well as forms of computing to create artificial neural networks and understand how our brains store and retrieve information.

This gives axons enough energy to carry out nerve impulses to the brain and other parts of the body, keeping them healthy and functional.

Initial results detected promising neuron spikes or nerve impulses and the patient is recovering well, he said.
