Forms: see palaeo- comb. form and cerebellum n.

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: palaeo- comb. form, cerebellum n.

Etymology: < palaeo- comb. form + cerebellum n., after German Palaeocerebellum (L. Edinger 1910, in Anatomischer Anzeiger 35 321). Compare neocerebellum n.

Anatomy.
