Abstract: As a vital part of human body, the brain executes junior and senior function through coordination and interaction of different functional regions. Modern scientific research showed that there were many human brain functional networks in the resting-state. The resting-state functional magnetic resonance imaging technology, which was getting more and more mature, taking opportunities for brain functional networks and was widely used in nervous and mental diseases, providing new methods and ideas for the diagnosis and assessment of nervous and mental diseases. This paper focused on the brain mechanism research methods based on resting-state networks and its application in nervous and mental diseases.

Key words: resting-state, brain networks, functional magnetic resonance imaging, nervous and mental diseases, brain mechanism, review
