Determination of the exact location and extent of a brain area at an individual level is crucial but challenging in in-vivo neuroimaging studies. We developed an analysis pipeline to parcellate the primary auditory cortex and its vicinity at an individual level with diffusion tensor imaging. Resulting three clusters, the central cluster and the two other flanking clusters, exhibited distinct functional connectivity patterns with the rest of the whole brain indicating that these clusters contribute to different functional networks.
