Researchers at UCSD say they developed a neural implant that can gather information about activity deep inside the brain while sitting on its surface.The UCSD team used a thin, transparent and flexible polymer strip packed with a dense array of graphene electrodes. They tested the technology in transgenic mice and say it brings them a step closer to building a minimally invasive brain-computer interface (BCI) that provides high-resolution deep neural activity data by using recordings from the brain surface.
“We are expanding the spatial reach of neural recordings with this technology,” said study senior author Duygu Kuzum,…
