fMRI can be used to detect the functional areas of human brain in vivo, which is helpful for neurosurgeons to make accurate pre-surgical plans. Due to the individual differences of the brain, the topography of different functional areas will vary across subjects. The purpose of this study was to construct group functional probability maps of different functional areas based on a large database of normal subjects. It has the potential to help neurosurgeons to make accurate pre-surgical plans and to improve the functional outcome of patients after surgery.
