Summary In the intact, unanesthetized, freely-moving cat the Purkinje cell activity driven by the mossy fiber system presents phasic increases in coincidence with movements of wakefulness or desynchronized sleep. Its rate of discharge may range between wide limits. In contrast, activity driven by the climbing fiber system varies between much more restricted limits. In the absence of movements its rate of dischange is higher during the desynchronized stage of sleep as compared to the synchronized one. In coincidence with the phasic events of paradoxical sleep the rate of discharge presents often a decrease. Some units, which have been assumed to be mossy and climbing fiber afferents, have a behavior similar to the mossy and climbing fiber driven activity, cespectively. Some characteristics of olivo-cerebellar neurons have been presented. A possible role of the mossy fiber and climbing fiber systems, respectively for phasic and tonic functions, is discussed. The pattern of activity during sleep is discussed in relation to the pattern observed in other brain areas. It is suggested that the cerebellum contributes to the collapse of the postural tonus which occurs during paradoxical sleep.
