Abstract: The study of brain science is one of the difficult problems of human scientific research, and memory is one of research hotspots of brain science. In the past, the focus is the structural research for memory, and the functional research is becoming the focus for memory now. In order to provide effective reference for memory research, we summarized the methods in our study on brain memory researches where the functional research is emphasis. Meanwhile, we put emphasis on memory networks and discuss the results and conclusions. We believe the methods of brain memory functional networks can provide the help and reference for memory researches.
