Building block of a programmable neuromorphic substrate: a digital neurosynaptic core

Left: neurosynaptic core measures 2mmx3mm, consisting of axons (rows), dendrites (columns), synapses (row–column junctions), and neurons that receive inputs from dendrites. Right: test board that interfaces with the chip via a USB 2.0 link. (Credit: J. V. Arthur et al./International Joint Conference on Neural Networks)
