researchers have successfully demonstrated how it is possible to 1 graphene - a two-dimensional form of carbon - with neurons, or nerve cells, while maintaining the integrity of these vital cells. the work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of 2 functions for amputee or paralysed patients, or for individuals with motor 3 such as epilepsy or parkinson's disease. the research, published in the journal acs nano, was an interdisciplinary 4 5 by the university of trieste in italy and the cambridge graphene centre.
 
6, other groups had shown that it is possible to use treated graphene to interact with neurons. however the signal to noise ratio from this interface was very low. by developing methods of working with untreated graphene, the researchers retained the material's electrical conductivity, making it a significantly better electrode. 
 
"for the first time we 7 graphene to neurons directly," said professor laura ballerini of the university of trieste in italy. "we then tested the ability of neurons to generate electrical signals known to represent brain activities, and found that the neurons retained their neuronal signalling properties unaltered. this is the first 8 study of neuronal synaptic activity using uncoated graphene based materials."
 
our understanding of the brain has increased to such a degree that by 9 directly between the brain and the outside world we can now harness and control some of its functions. for instance, by measuring the brain's electrical impulses, sensory functions can be recovered. this can be used to control robotic arms for amputee patients or any number of basic processes for paralysed patients - from speech to movement of objects in the world around them. alternatively, by 10 with these electrical impulses, motor disorders (such as epilepsy or parkinson's) can start to be controlled.
 
scientists have made this possible by developing electrodes that can be placed deep within the brain. these electrodes connect directly to neurons and transmit their electrical signals away from the body, allowing their meaning to be 11.
