    【Abstract】 Functional magnetic resonance imaging (fMRI) could probe the brain activity of cognitive process effectively when combining with blood oxygenation leveldependent (BOLD)and echo planar imaging(EPI),and it has higher differentiate ability. In recent years, fMRI has been applied to study cognitive ability, such as sensation, perception, learning, thinking and language and etc., and showed great potentiality on research of cognitive ability of brain and neuro-locating.

    【Key words】 Functional magnetic resonance imaging; Brain; Cognitive ability

    近20年来，以功能性磁共振成像(functional magnetic resonance imaging, fMRI)为代表的脑认知功能成像技术得到了巨大发展 ......
