Giving Your Brain a Voice: Engineering Sensors That Listen to Brain Cells
b'The human brain is composed of billions of cells that communicate through chemical and electrical signals. LLNL microelectrodes can interface directly with the brain to allow us to monitor and manipulate the dynamics of these brain signals. LLNL microelectrodes are flexible and microfabricated in dense arrays that allow them to collect large amounts of information over long periods of time in the body. Scientists Anna Belle and Allison Yorita go over how these arrays are microfabricated and their diagnostic and therapeutic applications.
