Pethia tiantian Pethia tiantian Pethia tiantian is a species of cyprinid fish that has only been recorded from streams in the vicinity of Putao in the far north of Myanmar. It grows to a length of SL. It is generally brownish with a dark vertical bar just behind the operculum and a round dark blotch on the caudal peduncle. Other "Pethia" species are similarly marked but "P. tiantian" can be distinguished by its longer lateral line, reaching all the way back to the base of the caudal fin. "P. didi", a similarly marked species found in the same drainage basin, differs from
Cerebellar peduncle the superior peduncle. They terminate in the hind limb region of the cerebellar cortex. The tectocerebellar tracts emerge from the superior and inferior colliculi on both sides, terminating in the intermediate vermis (culmen, declive, folium, tuber, pyramid) and the lobulus simplex. The function of the tectocerebellar tract is not known, but it is widely believed to mediate visual and auditory reflexes. Cerebellar peduncle Cerebellar peduncles connect the cerebellum to the brain stem. There are six cerebellar peduncles in total, three on each side: The peduncles form the lateral border of the fourth ventricle, and form a distinctive diamond the middle
