- Аннотация: The field potentials in response to stimulation of the cerebral sensorimotor cortex and of the limb nerves were recorded in the granular layer of the cerebellar paramedian lobule in nonanesthetized cats. The field potentials contained long-latency components, i.e. slow negative waves generated by granule cells. The long-latency component to nerve stimulation was recorded both inside and outside the projection area of the given limb, while the cerebral stimulation with a low intensity (1.8-2.5 thresholds) evoked this component in the given projection area only. The long latency component to cerebral stimulation followed higher rates and was less sensitive to the action of the barbital anaesthesia than the component following the nerve stimulation. Simultaneous cerebral and nerve stimulation evoked the long latency component equal to the sum of the separate components. It is suggested that slow conduction spinal and cerebral inputs form separate mossy fibres - granule cell pathways.
