These fibres probably form the m... more »ajority of those which arise from the Purkinje's cells. The nucleus sends fibres to the inferior olive of the opposite side, and also through the superior cerebellar peduncle to the red nucleus and optic thalamus of the opposite side. The roof nucleus and the nucleus dentatus (with its accessory nucleus globosus and emboliformis) are thus concerned in receiving impressions from is CORPUS OENTATUM SUP CER PED INF.

The distribution of the fibres from the nucleus of Deiters is considered in relation to the auditory nerve, and is of special importance as regards the movements required for the maintenance of the equilibrium. The middle peduncle of the cerebellum is formed by the superficial, middle, and deep fibres of the pons, and arises mainly from the groups of cells which lie among these fibres (the nuclei pontis). These cells are also in connection with the fibres from the frontal, temporal, and, to some extent, the parietal lobes of the cerebrum, which either end themselves or send their collaterals among the cells. The fibres from these cells pass to the cortexof the lateral lobe of the cerebellum. (A few fibres of this peduncle pass towards the nucleus pontis of the sam...« less
