Graphene Implants Can Hear Your Brain Whisper

Abstract

For years the Neural sensing and stimulation was the mainstay of neuroscience research, brain computer interactions and therapeutic clinical neuromodulation applications. The traditional systems used for neural stimulation have to depend on on sharp metal microelectrodes with meagre electrochemical properties that leads to widespread tissue injury and suggestively worsen the long-standing steadiness of implants [1]. There is substantial growth in the frame of information regarding the human brain. Several queries are still unreciprocated. For decades, scientists have been using electrodes to record the brain s electrical activity mapping in various regions of brain to comprehend its functions. The disadvantage of such electrode arrays is that they are able to perceive the activity over a certain threshold frequency.
