SIMILARITIES BETWEEN EMBOLIC STROKE AND PERCOLATION PROBLEMS

We discuss a recently developed embolic stroke model in relation to models of percolation. When descibing embolic stroke, it is important to know if blood flow can travel from the major arteries to the arterioles supplying the brain. In this sense, the onset of stroke bears some similarity to the central question of percolation theory. The order parameter for the percolation transition is found, and the percolation threshold is investigated. We discuss possible extensions to the model.
