Reward-modulated spike-timing dependent plasticity (RSTDP) can be modelled as STDP with an eligibility trace. RSTDP provides an explanation for how a reward that occurs a short time after the stimulus (i.e., outside the STDP learning window) can nevertheless cause a change in the synaptic strengths. The activities of two neurons, labelled A and B, are being recorded and are observed to have similar average spiking rates. Both neurons are observed to change their firing rates in response to both a stimulus and a reward. Describe how the timing of the delivery of the reward could be manipulated so that, during the learning period, the activity of neuron A increased but the activity of neuron B decreased.
