Northwestern University researchers report they have printed flexible “artificial neurons” that generate realistic electrical spike patterns and can trigger responses in living mouse brain tissue. The team says the work, published April 15 in Nature Nanotechnology, could help advance brain-machine interfaces and more energy-efficient, brain-inspired computing.
