Lawrence Livermore National Laboratory was funded by the Department of Defense's Defense Advanced Research Projects Agency (DARPA) to develop an implantable neural interface with the ability to record and stimulate neurons within the brain for treating neuropsychiatric disorders. The technology will help doctors to better understand and treat post-traumatic stress disorder (PTSD), traumatic brain injury (TBI), chronic pain and other conditions.
The project is part of DARPA's SUBNETS (Systems-Based Neurotechnology for Emerging Therapies) program. The agency is launching new programs to support President Obama's BRAIN (Brain Research through Advancing Innovative Neurotechnologies) Initiative, a new research effort aimed to revolutionize our understanding of the human mind and uncover ways to treat, prevent and cure brain disorders.
The LLNL Neural Technology group will develop an implantable neural device with hundreds of electrodes by leveraging their thin-film neural interface technology, a more than tenfold increase over current Deep Brain Stimulation (DBS) devices. The electrodes will be integrated with electronics using advanced LLNL integration and 3D packaging technologies. The goal is to seal the electronic components in miniaturized, self-contained, wireless neural hardware. The microelectrodes that are the heart of this device are embedded in a biocompatible, flexible polymer.
LLNL and Medtronic are collaborating with UCSF, UC Berkeley, Cornell University, New York University, PositScience Inc. and Cortera Neurotechnologies on the DARPA SUBNETS project. Some collaborators will be developing the electronic components of the device, while others will be validating and characterizing it.
