Vignette is typical for Parkinson's disease. Area D is the substantia nigra.

does anyone know what A, B, C and E are pointing to? I figured D is substantia nigra since it's the correct answer.

upstairs_bumblebee  A/B - i think both of these are just thalamic nuclei; C -> STN; D -> substantia nigra; E -> hippocampus +6
