Biologically Plausible Dopamine-Modulated STDP Model of Pavlovian Learning in Spiking Neural Networks

A DA-modulated STDP rule is proposed in which increasing DA progressively biases plasticity toward potentiation while receptor saturation limits further DA effects beyond a critical concentration, providing a biologically grounded model of DA-dependent plasticity and offering new insight into how abnormal dopamine signaling can impair learning in neurological disorders.
