Surface brain waves tapped at UC San Francisco Flexible thin-film electrodes developed at Lawrence Livermore National Laboratory have been used at UC San Francisco to record human brain activity on the surface of the brain’s hippocampus area. “We’ve developed an enabling technology for demonstrating a phenomenon that wasn’t really possible before,” says LLNL’s Implantable Microsystems Group Leader Razi Haque, “this challenge required creation of novel, conformable and higher-density electrodes that allows them to be more flexible and wrap around specific, deep regions of the brain. This study is validation that the approaches we’re using are getting us consistent, usable and useful data.”
