Artificial Intelligence (AI) aims to simulate information storage and processing mechanisms and other intelligent behaviors of a human brain, so that the machine has a certain level of intelligence. With the rapid development of the new generation of information technology, such as the Internet, big data, cloud computing, and deep learning, researches and applications of AI have made and are making important progresses. In this paper, the historical integration and evolution of computer science, control science, brain-inspired intelligence, human brain intelligence, and other disciplines or fields closely related to AI are analyzed in depth; then it is pointed out that the research results on the structure and functional mechanism of brain from neuroscience, brain science and cognitive science provide some important inspirations for the construction of an intelligent computing model. Moreover, the drives and developments of AI are discussed from the aspects of logic model and system, neuron network model, visual nerve hierarchy mechanism, etc. Finally, the development trend of AI is prospected from the following five aspects: the computational theory of the Internet, the integration of AI calculus and computation, the model and mechanism of brain-inspired intelligence, the impetus of AI to neuroscience, and the algorithm design of feedback computation and the energy level of the control system.
