Identification of the Substantia nigra pars compacta (SNc)/ventral tegmental area (VTA) complex on study-specific fiber orientation distribution (FOD) template. Axial, sagittal and coronal sections showing the putative boundaries of SNc/VTA complex. SNc/VTA region was defined as an area of marked hypointensity situated anteriorly to the red nucleus (Rn), posteriorly to the crus cerebri (cc) and inferiorly to the subthalamic nucleus (*). S: superior; I; inferior; R: right; L: left; A: anterior; P: posterior.
