Objective:
To design a set of functional magnetic resonance imaging (fMRI) tasks to activate the major Chinese language functional areas.
Methods:
Eight volunteers and 3 patients received fMRI studies with the tasks of semantic judgment, word reading and listening comprehension. Brain activation map of each task was obtained after standard fMRI data processing.
Results:
The fMRI examination with 3 tasks activated middle frontal gyrus (BA 9), Broca area and Wernicke area respectively.
Conclusion:
A set of fMRI examinations, including semantic judgment, word reading and listening comprehension, can activate the major Chinese language functional areas steadily and may be used as a preoperative localizer of language areas.
