This Soft Robot Unfurls Inside the Skull

An octopus-like soft robot can unfurl itself inside the skull on top of the brain, a new study finds. The novel gadget may lead to minimally invasive ways to investigate the brain and implant brain-computer interfaces, researchers say. In order to analyze the brain after traumatic injuries, help treat disorders such as seizures, and embed brain-computer interfaces, scientists at times lay grids of electrodes onto the surface of the brain. These electrocorticography grids can capture higher-quali
