Аннотация:This work deals with the tasks and relevance of mathematical computer modeling of biological systems and, in particular, simulation modeling.A discrete computer mathematical model presented is suitable for the ischemic stroke pathogenesis outlook engaged with an appropriatecomputer program described. For the first time, the results of stroke modeling performed by stochastic Monte Carlo method with the brainneurovascular units as elementary structures of the system have been proposed. Conclusions are drawn taking into account an appliedpharmacological potential of the model for the current preclinical trails requirements.
