Researchers from the University of Michigan have developed a neural probe with an unprecedented number of micro-LEDs and recording sites integrated into the same neural device, enabling neuroscientists to gain new knowledge about how the brain operates. The hectoSTAR probe device allows scientists to record greater areas of the brain and interactions between these areas, which could lead to important insights into treating neurological disorders. Euisik Yoon, Ph.D., professor, and director of the lab that developed the probe, explores the device and future research.
