Automatic segmentation and parcellation of the PAG based on fMRI aquired at 7T. PAG segmentation is based on the identification of the cerebral aqueduct and delineation of nearby gray matter. Segmentation is based on a spatial decomposition of voxels in the PAG, based on angular and rostro-caudal position. For details, see Kragel et al. 2019 below.
