The human brain, which serves as the command centre for the central nervous system, regulates all of the body's activities and retains memories, while Blue Brain, the world's first virtual computer, is the first to perform as a suitable application of a synthetic human brain. Reverse engineering is often used to enable cellular level implementation and reconstruction of the human brain inside a simulation. With technological advances, humans are typically maintained as the ultimate source of data and discovery, ensuring that intellect is seldom lost. IBM's blue gene supercomputer allows for a quantum leap in the level of detail that can be modelled in the brain. This technique pinpoints the brain's basic principles, functions, and capacities. This review article includes comprehensive information on the comparison of real and simulated brains, artificial brain implementation, and the different stages involved in constructing a simulated brain using Artificial Intelligence.
