Based on the similarity between the neural and the immune networks, a modified PDP model is adopted to simulate the idiotype networks of the immune system. Major modifications peculiar to immune networks are the introduction of time delays and the bilateral and asymmetric interaction between units. Simulation results show nonlinear behaviors of networks such as hard oscillations and chaos. The behaviors are closely related to the structure of networks. It is suggested that the analysis of the immune system can inspire new scheme in parallel distributed information processing.
