WebMay 17, 2024 · For example, in monkeys, the portion of the cerebellum that is housed by the floccular fossa is composed of the petrosal lobule (part of the dorsal paraflocculus), while in other mammals it is ... The flocculus is a part of the vestibulo-ocular reflex system and is used to help stabilize gaze during head rotation about any axis of space. Neurons in both the vermis of cerebellum and flocculus transmit an eye velocity signal that correlates with smooth pursuit. The idea that the flocculus is involved in motor learning gave rise to the “flocculus hypothesis.” This hypothesis argues that the flocculus plays a key role in the vestibulo-ocular system, most i…

Also the dorsal paraflocculus, adjacent to the ventral paraflocculus, has oculomotor functions. Although as yet relatively little explored, its function seems to differ from that of the neighbouring vestibular cerebellum. chocolat michel cluizel
