1937 O. Larsell in Arch. Neurol. & Psychiatry 38 606 The boundaries, especially that between the archicerebellum and the paleocerebellum, cannot be sharply fixed, but in general the archicerebellum should include the flocculonodular lobe and the basis cerebelli, with part of the anterior lobe of the corpus cerebelli and possibly part of the posterior lobe.

1972 M. L. Barr Human Nerv. Syst. x. 161/1 The vestibulocerebellum or archicerebellum is the oldest part, constituting the entire cerebellum of fishes; it is concerned with maintenance of the equilibrium.

1980 Jrnl. Cell Biol. 87 109/2 Cholinergic glomeruli are found primarily in the archicerebellum, folia IX and X.

2000 Proc. National Acad. Sci. U.S.A. 97 2335/1 We speculate that activations in the older cerebellar regions (vermis, fastigal nucleus, and archicerebellum) are more directly related to vegetative and affective aspects of the experience of thirst.
