Brain Struct Funct (2008) 212:443–463 Fig. 2 Series of frontal sections stained for myelin and arranged from anterior (upper left) to posterior (lower right), with corresponding coordinates given in millimeters anterior to the posterior commissural level (Table 1; case Hb4). The pallidothalamic ﬁbres are seen from their emergence from the GPi (al and ﬂ, levels A 21.0– A 13) to their entry into the thalamus (ft, levels A 15–A 12). The cerebellothalamic (fct) tract is shown at its most posterior entrance into the thalamus (near the VPM, level A 6.0) and more anteriorly, into VLp (level A 7.5). Other ﬁbre tracts (mtt, fx, ap, ot, and ac) are also clearly recognizable. Scale bar (in upper left panel): 3 mm 447 123
