Fig. 2. Callosal streamlines’ passing location on the mCC for selected cortical regions. (A) Schematic diagram of generating group mCC location for a cortical region. As illustrated, the passing location on the mCC can overlap to some degree for two different cortical regions (e.g., area 9-46d on the lateral prefrontal cortex and area 9m on the medial prefrontal cortex). (B) The resultant group mCC pattern maps are displayed for selected HCPMMP regions on the left hemisphere (red in the solid box): area 4 on the primary motor cortex, area 2 on the somatosensory cortex, area TE1p on the lateral temporal cortex, area 7AL on the lateral parietal cortex, and area POS2 on the medial parietal cortex. The HCPMMP regional abbreviation is included in the bracket.
