Abstract: The large-scale brain model which simulates brain on a basis of computational neuroscience principle or graph theory has great significance and application value in brain science research and artificial intelligence. A proper large-scale brain model will contribute to exploring and understanding the underlying mechanisms of brain and the reasons of neurological diseases, and will also greatly put forward the transformation from the current weak artificial intelligence to strong one. Thus, research on large-scale brain models has received extensive attention all over the world in the past decades. By reviewing latest research literatures on large-scale brain models, this paper reports the current progress of large-scale brain models. Firstly, it gives a clear definition of large-scale brain models, outlines the categories of large-scale brain model, and introduces the relevant fundamental theories that is necessary for understanding large-scale brain models. Secondly, the effective modeling strategies of large-scale brain models are summarized, and the detailed modeling methods of several representative large-scale brain models and its application are introduced. Finally, it summarizes the shortcomings and difficulties encountered in the field of large-scale brain models, and predicts the possible development and application directions of large-scale brain models.
