Figure 1.
Semi-quantitative assessment of neuronal loss in the substantia nigra and subthalamic nucleus between CBD-CBS (blue), CBD-RS (purple) and PSP-RS (red). The lateral portion of the substantia nigra refers to the ventrolateral neuronal population (A9) and the medial substantia nigra corresponds to the ventral tegmental area (A10). Pathological scoring scheme: 0 = none; 1 = mild; 2 = moderate; 3 = severe; 4 = almost complete; Black line = median pathological score; white line = mean; *P < 0.05; **P < 0.001.
