Effects of oscillatory activity on coherence patterns in the cerebellar cortex

The cerebellum is getting more recognized as a rhythm generator, producing oscillations in different frequency bands. While the cerebellum has been associated with motor control, sensory perception, and cognition, the functional role of the granule cell layer oscillations is still elusive. Using awake, unrestrained rats, oscillations were recorded with multiple electrodes in the granule cell layer of posterior lobe of the cerebellar cortex. The purpose of this study was to investigate the effect of oscillations on pattern activity in the granule cell layer. In this study we show that cerebellar oscillations influence the synchrony of local field potential activity across the cerebellar cortex. These oscillations in the frequency range of 6-11 Hz were found to synchronize patterns of local field potentials organized along the coronal plane of the cerebellar cortex. Cerebellar oscillations of the granule cell layer synchronize local field potentials and are integral to the intrinsic circuitry of the cerebellum and playa functional role in spatially organizing cerebellar networks
