PFvl connections in the human in more detail. a, Termination point of tracts seeded in EC and SLFIII in the PFvl in Talairach space in an axial slice and a sagittal slice. Boxes represent SEM for each dataset. Connections from the SLF target a significantly more posterior, dorsal, and lateral part of PFvl than connections from the EC. b, Proportion of projections from EC, SLFIII, and SLFII to human POp and the more anterior remainder of PFvl.
