In lower vertebratestnere is a strong direct connectionfrom the optic centers of the mid-brain to the cerebellum (tractustcctocerebellaris). This connec-tion is reduced in man (thoughstill present, as Edinger has re-cently shown), probably beingfunctionally replaced by the midbrain-olivary path tothe cerebellum and by cortical connections. The in-ferior olive receives ascending fibers from the wholelength of the spinal cord (Goldstein), descending fibersfrom the optic tectum of the midbrain (by the centraltegmental tract) and fibers from the nuclei of the funic- central Tegmental Tract.
