In 50 dogs stimulations of the flocculonodular lobe and parts of the vermis of the cerebellum were carried out by a square wave stimulator and evoked potentials recorded through depth electrodes from a number of structures of the limbic system oscillographically. It was observed that the posterior part of the paleocerebellum and flocculonodular lobe project to limbic structures of the frontal and temporal lobes and to the hypothalamic regions. The anterior part of the paleocerebellum projects only to the orbital cortex, hippocampus and hypothalamus. Neocerebellar regions of the vermis have no projections to the limbic system, except possibly to the hypothalamus.
