| Abstract: | Blood oxygenation-level dependent functional MRI (BOLD-fMRI) realizes the functional organization of the visual system in humans. There are many important fruits in the field. The paper will talk about parallel processing and hierarchial organization in the visual information processing in detail. Also,we will summarize the development about functional MRI in the localization of the visual cortex,colour identification and motion perception in humans. |
