Brain waves can be read by the Graphene made electronic arrays with high resolution

Brain reading might be every person’s dream but the creator had already made a top-coded neural system that cannot be breached by any other individual and in some cases not even by the same person. Though scientifically we know each part of the brain and are also familiar with its functional limitations, but when it comes to a case when the neurologically disabled person cannot communicate normally with the normal individual.

But the discovery of this new electrode arrays for evaluating signals straightaway from the brain enabled scientist to examine the neurological disease and also let the critically disabled patient communicate. Using conventional process or materials it was complex to place the transistors amid high density on a neural probe in order to collect maximum neurons at the same time. Following this conventional method had loads of noise introduction that actually covers the expected signal and delivers deprived results.

The brain reading array made up of graphene transistors and developed by the European researchers can record various types of waves generated by the brain such as slow waves, brain activity, and visually inducing signals based on the epileptic seizure.

Previously the material used for detecting high-density recording is known as SGFETs which means solution-gated field effect transistors. However, the researchers experienced many challenges while finding the good quality material. Graphene is highly biocompatible and flat sheet of carbon that is only one atom thick produces a low amount of noise and while interpreting with the brain it generates a strong signal when sampled.

The researchers believe that this technology has proved to be a potential solution in understanding the brain. It will also help in understand the neurological conditions of the human brain.

The overall research and its output was the result of combined efforts made by some Flagship partners such as The Biomedical Research Networking Center in Bioengineering, Biomaterials and Nanomedicine (Spain), Technical University of Munich (Germany), Catalan Institute of Nanoscience and Nanotechnology (Spain) and IDIBAPS– Institut d’Investigacions Biomèdiques August Pi i Sunyer (Spain).

So now let’s just hope the neurologically disabled person will be soon analyzed and cure with this advancement in the medical field.
