Modeling the diffusion of nitric oxide produced by neuronal cells in brain ischemia.

Mathematical models of NO diffusion were established to investigate the role of nitric oxide produced by neuronal cells in brain ischemia. Results showed that NO synthesized at early stage of brain ischemia could diffuse to a far more distant than that of a resting state. We speculate the roles of NO produced by neuronal cells in brain ischemia might have two different effects, depending on its concentration.
