The flocculus is a very small lobe part located at the bottom of the cerebellum underside, such a part to hay. and one to the left. about the middle line. The flocculus connects with the help of the flocculus arm to the equally modest, equally unassuming, cerebellar nodule (nodulus cerebelli ). The flocculus and nodulus together form the vestibulocerebellum, which is the most original part of the cerebellum.

The flocculuscortex receives (afferens) some signals directly from the balance organ, but above all from small core areas in the upper part of the brainstem, nuclei that divert visual information. Flocculus transmits (Purkinje neuron) signals (efferens) to the vestibular nuclei.
