Scientists build living ‘neurobots’ that grow their own neural networks

Researchers at Tufts and Harvard have built tiny living "neurobots" — biological organisms made from frog embryo tissue implanted with neuron-forming cells that grow their own functional neural networks. These neurobots move more actively and follow more complex paths than standard biobots, and surprisingly express genes linked to visual processing, raising the possibility they could one day respond to light. The findings suggest nervous systems are far more adaptable than previously believed.
