Vision research is very important to reveal the mystery of brain. Functional magnetic resonance imaging(fMRI) is a method for measuring hemodynamic responses to changes in neural activity in the brain. As the activity in the human brain can be observed by fMRI non-invasively with spatial resolution of a few millimeters and temporal resolution of less than a second, fMRI has become an important approach to human brain research since the 1990s. The recent application of fMRI to visual studies has begun to elucidate how the human visual system is anatomically and functionally organized. There is much more work to do to investigate the neural mechanism of the higher-level functions such as mind、attention and memory.
