Graphene shown to safely interact with neurons in the brain

Jan 30, 2016

Researchers have shown that graphene can be used to make electrodes that can be implanted in the brain, which could potentially be used to restore sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as Parkinson’s disease.

Researchers have successfully demonstrated how it is possible to interface 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 sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as epilepsy or Parkinson’s disease.

The research, published in the journal ACS Nano, was an interdisciplinary collaboration coordinated by the University of Trieste in Italy and the Cambridge Graphene Centre.

Previously, 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 interfaced 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 functional study of neuronal synaptic activity using uncoated graphene based materials.”

  • It is necessary to notice that functions of projections of Carbon contain synchronous communication of the main genetic variable phase functions in genetic structure. In this case, the spot of a projection of Carbon is result of a certain final product of combinations of variable phases of genetic structure. Artificial placement of a spot of Carbon in structure of neural communication promotes additional accumulation of functions of phase projections of genetic structure of neurons. This implant allows to distort data of combinations of phase functions of structure of neuron. Carbon – final structure of the bases of Nitrogen. This structure contains functions for a condition of division and formation of external phase functions.

    In the conditions of epilepsy and Parkinson’s illness there is a lack of Oxygen phases in functional genetic structure. Process of oxygen phases is broken in a limit of mirror functional divisions of structure of Hydrogen and Oxygen. In this case, projections of phase functions are displaced towards a spot of the Nitrogen passing into structure of a spot of Carbon.

    My results of researches of genetic structure define twelve functional phases. The structure of a spot of a genetic symbol contains twelve functions. These data assume each phase value in various functional structures.

  • I’d like to thank you for your learned contribution Alexander Khripkov; I only wish I could understand it. Perhaps you’d like to elaborate please Alexander.

  • This has been bubbling under for a little while and is more great news.

    I’ve posted a couple of times now on the remarkable effectiveness of deep implant neural pacemakers in the treatment of Parkinsonism and epilepsy, etc.. Reliable, nano, bio-compatible electrodes transform the cost effectiveness of these types of treatments.

    Retinal and cochlear implants can rush ahead in their finesse…the replacement hippocampus (if we can ever understand its complexities) can rescue those of us contemplating amnesia or dementia.

    This technology could go badly wrong, though, or fall foul of an invasive scienti-po-mo virus as Alexander was clearly trying to warn us.
