The green pick is in the middle cerebellar peduncle, which is formed by transverse pontine fibers (asterisk), which are axons of contralateral pontine nuclei. The trigeminal nerve (V) exits the brainstem by passing through the middle peduncle. The arrow points to the primary fissure that divides the cerebellum into rostral and caudal lobes.

cerebellum and medulla oblongata of a dog.From medial to lateral, cerebellar nuclei are: fastigial (F), interpositus (I), and dentate (D). Fibers of the caudal cerebellar peduncle (red arrow) are evident before they turn dorsally into the cerebellum. (The term "restiform body" is a synonym for caudal cerebellar peduncle.).
