New technique for recording neuronal activity in vivo

In a collaboration with groups at the Stanford University, CA, USA, and the Crick Institute, UK, the Bio Engineering Lab headed by Andreas Hierlemann developed a new technique to measure neuronal signals in live brains. The technique combines bundles of long metal wires of a few micrometer diameter with planar silicon-based CMOS microelectronics technology. The new devices show excellent performance in reading out neuronal activity in awake moving mice.
