A soft brain implant that unfurls under the skull could give doctors a less invasive way to monitor patients’ brain activity — and maybe allow people to directly control technology with their minds.
The challenge: Placing an electrode array on the surface of the brain allows scientists to see neural activity in far more detail than is possible with electrodes outside of the skull.
Known as “electrocorticography,” this technology was initially developed to treat people with epilepsy, but it’s also been used in research for other types of neurological disorders and in the development of brain-computer interfaces.
