Brain mapping is a technique used to alleviate the tedious and timeconsuming process of annotating brains by mapping existing annotations from brain atlases to individual brains. We introduce an automated surface-based brain mapping approach. After reconstructing a volume data set (trivariate scalar field) from raw imaging data, an isosurface is extracted approximating the brain cortex. The cortical surface can be segmented into gyral and sulcal regions by exploiting geometrical properties. Ourdoi:10.1007/3-540-30790-7_3 fatcat:jc24lmqgmzf7doz4n4kgruw3yu
