(2) The Middle Peduncles are formed by processes which grow from the cortical cells of the cerebellum to the nuclei of the Pons and also by processes from the cells of the Pontine nuclei to the cerebellum. They are probably connected indirectly with the frontal lobes through the fronto-cerebellar fibres which lie in the inner third of the crusta. (3) The Inferior Peduncles are formed by : (a) Processes from the cerebellar cortex to the cord (descend- ing cerebellar tract); (6) Processes which end in the opposite olive ; (c) Processes which grow in from Clarke's column (direct cerebellar); (d) Processes from the cells of the sensory nuclei of the postero-mesial and postero-lateral tracts (nucleus gracilis et cuneatus)..
