Reconstruction of aldolase C compartments through out the cerebellar cortex. Continuity of the compartments in the rostrocaudal direction was determined by accurate tracing of individual compartments on serial sections and then plotted on a map of the unfolded cerebellar cortex (see Materials and Methods). Several new compartments were discovered (marked by asterisks prefixed to their proposed names) beyond those identified previously by Hawkes and Leclerc (1987), Voogd et al. (2003), and Voogd and Ruigrok (2004). A positive compartment and its laterally neighboring negative compartment usually have the same name with different suffixes (+, positive compartment; -, negative compartment). The intensity of the gray color approximately corresponds to the intensity of labeling. The dotted line on the left indicates the rostrocaudal boundary of the compartment pattern (see Results). Arrowheads indicate areas in which the molecular layer is absent, one of which in the caudal apex of lobule VIc-crus I approximately coincided with the rostrocaudal border. I-X, Lobules I-X; a-c, sublobules a-c; CP, copula pyramidis; Cr I, crus I of ansiform lobule; Cr II, crus II of ansiform lobule; DPFL, dorsal paraflocculus; FL, flocculus; Par, paramedian lobule; pf, primary fissure; Sim, simple lobule; VPFL, ventral paraflocculus.
