Graphene-based implant overcomes technical limitation to record brain activity at extremely low frequencies
Researchers in Barcelona have developed a graphene-based implant able to record electrical activity in the brain at extremely low frequencies and over large areas, unlocking the wealth of information found below 0.1 Hz. The prototype was developed at the Barcelona Microelectronics Institute (IMB-CNM, CSIC) and the Catalan Institute of Nanoscience and Nanotechnology (ICN2, a BIST and CSIC centre), and was adapted for brain recordings in collaboration with the August Pi i Sunyer Biomedical Research Institute (IDIBAPS). Published in Nature Materials, the groundbreaking technology promises to enhance our understanding of the brain and pave the way for the next generation of brain-computer interfaces.
