Triplet-based STDP implemented on STOx synaptic devices. (a) An illustration of two biological neurons connecting via synapses. (b) Artificial implementation of STDP learning rules using STOx synaptic devices. Each data point and its deviation from mean (represented by bars) are collected by applying 100 cycles of identical pulses, where each cycle contains a RESET (for potentiation experiments) or SET (for depression experiments) pulse.
