I. Introduction
The brain is a complex temporal and spatial multiscale structure that gives rise to intricate molecular, cellular, and neural phenomena that together form the physical and biological basis of cognition. The brain can be understood as a complex system or network, in which mental states arise from interactions between different physical and functional levels [1]. Although the brain is one of the most functional nerves in human life, it is also not immune to health hazards. Stroke is a medical condition that attacks the performance of the human brain [2]. Strokes are caused because the brain does not receive enough blood flow which causes malfunction in the brain.
