Adjective
flocculonodular (not comparable)
(anatomy) Pertaining to the nodule and flocculus of the cerebellum.
Based on the surface appearance, three lobes can be distinguished within the cerebellum: the anterior lobe (above the primary fissure ), the posterior lobe (below the primary fissure), and the flocculonodular lobe (below the posterior fissure). Source: Internet
The flocculonodular lobe is the only part of the cerebellar cortex that does not project to the deep nuclei—its output goes to the vestibular nuclei instead. Source: Internet
