a Hohman [1] distinguished three discrete bundles of degenerated Purkinje cell axons in the white matter of the anterior vermis after lesions of the cortex of this area (Marchi method). The medial anterior vermis-fastigius bundle and the lateral anterior vermis-Deiters bundle are located in the vermis and terminate in these nuclei. b White matter compartments in the anterior lobe of the monkey cerebellum. The borders of the compartments A-D stain for acetylcholinesterase. The A (with Ax) and B compartments contain the Purkinje axons of Hohman’s anterior vermis-fastigius- and Deiters bundles, respectively
