| Abstract: | Funtional magnetic resonance images(fMRI)exhibit small defferences in the magnetic resonance signal intensity in positions corresponding to focal areas of brain activation.As a non-invasive and dynamic technique,fMRI has been a key method for visualizing the working brain,and uncovering the topographical organization of the human brain,and understading the relationship between brain and mind.In this paper,basic principles and applications in the study of fMRI are introduced.Then the main steps of neuroscience study with fMRI are presented respectively.Finally,recent progresses and prospects of fMRI are reviewed. |
