"Like neurons, coated insulating layer... ions migrate across insulating layer into nanowire like neurotransmitters across synapses... high-order cognitive function: learning and memory... selectively strengthen(and weaken synaptic pathways similar supervised learning brain... synapses strengthened if output close to desired result or pruned if not close... remembered previous signals >=7 steps"
