A chemically mediated artificial neuron

Brain–machine interfaces typically rely on electrophysiological signals to interpret and transmit neurological information. In biological systems, however, neurotransmitters are chemical-based interneuron messengers. This mismatch can potentially lead incorrect interpretation of the transmitted neuron Here we report a chemically mediated artificial that receive release neurotransmitter dopamine. The detects dopamine using carbon-based electrochemical sensor then processes sensory memristor with synaptic plasticity, before stimulating through heat-responsive hydrogel. system responds exocytosis from rat pheochromocytoma cells also releases activate cells, forming chemical communication loop similar interneurons. To illustrate potential this approach, show trigger controllable movement mouse leg robotic hand. An via hydrogel, be used
