neocerebellum Anat.
(niːəʊsɛrɪˈbɛləm)
[mod.L., f. neo- 1 e + cerebellum.]
The phylogenetically youngest portion of the cerebellum, comprising mainly its lateral lobes (‘hemispheres’).
| 1925 W. H. F. Addison tr. Villiger's Brain & Spinal Cord (ed. 3) 80 The hemispheres constitute the neocerebellum, and the vermis and flocculus constitute the palaeocerebellum. 1954 Jansen & Brodal Aspects Cerebellar Anat. vi. 384 We may appropriately close this discussion by commenting briefly on the much debated concepts paleocerebellum, comprising the vermis and the flocculus, and neocerebellum, comprising the cerebellar hemispheres... From the point of view of gross morphology these concepts may appear well founded. On the basis of fiber connections, however, a paleocerebellum and a neocerebellum sensu strictiori are not distinguishable. 1974 Encycl. Brit. Macropædia XII. 990/2 This new part of the cerebellum, or neocerebellum, coordinates skilled movements initiated at cortical levels. |
So neocereˈbellar a., of or pertaining to the neocerebellum.

Here homolateral hypotonia and atactic movements, asynergic and clumsy, appear, and when the dentate nucleus is involved tremor also develops. 1958 Jrnl. Neurophysiol. XXI. 3 Stimulation of some neocerebellar areas, however, resulted in equilibratory changes. |
