The halves of the flocculus refer to the caudal half and the rostral half, and they indicate from where fiber projections are received and the path in which a signal travels.

The caudal half of the flocculus receives mossy fiber projections mainly from the vestibular system and nucleus reticularis tegmenti pontis, an area within the floor of the midbrain that affects the axonal projections or images received by the cerebellum.

The amount of tissue supplied by the AICA is variable, depending upon whether the PICA is more or less dominant, but usually includes the anteroinferior surface of the cerebellum, the flocculus, middle cerebellar peduncle and inferolateral portion of the pons.

Pterosaurs may have had such a large flocculus because of their large wing size, which would mean that there was a great deal more sensory information to process . and recent studies of crocodilians and other reptiles show that it is common for sauropsids to achieve high intelligence levels with small brains.
