The researchers say identifying chemicals rather than electrical impulses will make for a more selective, precise instrument.
His neural-robotic leg will respond to electrical impulses from muscles in his hamstring.
FORBES: True Bionic Man Will Make History by Climbing One of the World's Tallest Buildings
Axons are connections that carry electrical impulses, or messages, from the neurons in the brain to the rest of the body.
One prediction from models of a chaotically beating heart is the break-up of regular electrical impulses into spirals, causing uneven contractions.
Gallium nitride, or GaN, converts electrical impulses to light and is grown on the surface of wafers made from sapphire or silicon carbide.
FORBES: How Silicon Will Spur A Boom In Solid-State Lighting
It is the movement of potassium (and also sodium) ions that causes the electrical impulses that nerve cells carry including the impulses found in slow-wave sleep.
It occurs when the heart beats with rapid, erratic electrical impulses.
Images are fed into a lollypop-like device that Craig holds in his mouth, this transforms the pictures into electrical impulses that he can feel on his tongue.
Just as importantly, the resulting nerve cells were able to conduct electrical impulses and could form the specialised junctions called synapses, by means of which nerve cells talk to each other.
One way this was found out was by vibrating whole frogs while recording the electrical impulses from particular cells in their inner ears that were suspected of responding to seismic stimulation.
Further into the future, if scientists better understand the neural bases of mental illnesses such as schizophrenia, it could be possible to also develop treatments by targeting groups of neurons with electrical impulses.
The measurements, translated to electrical impulses, would be delivered to the three vestibular nerves that emanate from the three semicircular canals, much like audio signals are delivered to the auditory nerve in cochlear implants.
All of the companies vying to emerge in the brain-wave market are using electroencephalograph, or EEG, technology, which measures the brain's electrical impulses in the forehead and has long been used to diagnose epilepsy and other brain disorders.
