The horizontal planes are projected on a sagittal section of the atlas 8.1 mm distant from the ventricular border (L8.1) in lower right panel. The pc and mcl levels are represented on the horizontal and sagittal maps by dotted lines. Scale bars (lower right panels): 2 mm Fig. 7 Series of frontal high- resolution proton density postmortem MRI (left column), myelin sections (middle column), and atlas maps (right column) of the same brain (Table 1; Hb5), at corresponding anteroposterior levels from posterior (lower panels) to middle part of the thalamus (upper panels). Coordinates indicated in the left column (A2.5, A5, and A7.5) correspond to millimeters anterior to the posterior commissural level. The cerebellothalamic tract (fct) can be identiﬁed, as well as the RN and several thalamic nuclei. Scale bars (left column): 10 mm internal capsule cannot be determined on myelin sections as it is embedded within the capsular ﬁbres, it seems to cross the internal capsule nearly horizontally and then runs dorsal to the subthalamic nucleus and ventral to ZI in a posteroventral direction, joining the al to form the fascic- ulus thalamicus (ft). The term ft thus characterizes all pallidothalamic ﬁbres entering the ventral thalamus, regardless of their ansal or fascicular origin.
