A novel adaptive resonance theory (ART) based on nitric oxide (NO) retrograde mechanism, named retrograde ART (ReART), is presented in this paper. Within the theoretical framework of the searching process in ART 3, we analyze the transmitter release among chemical synapses, and propose a novel search hypothesis which incorporates angle and amplitude information to decide whether an external input matches the long-term memory (LTM) weights of an active node or not. By introducing NO retrograde mechanism, the dynamic search and mismatch-reset cycle of ART 3 is improved. To avoid the potential phenomenon of pattern excursion in the node growing process, the forgetting mechanism is constructed. By incorporating the matched nodes and abandoning the erroneous nodes, the novel algorithm optimizes the node growing mechanism. The following simulations indicate that the proposed model has perfect classification, faster convergence and excellent disturbance rejection capability
