[Analysis of the regulatory mechanism of the rat cerebellum on the motor coordination in the time and space domain].
To elucidate the mechanism of the cerebellum on the regulation of coordinated movement in time and space domain, ninety-six Purkinje cell complex spike was simultaneously recorded utilizing ninety-six glass micro pipette electrodes. The complex activity of the bilateral cerebellum was symmetrically synchronized. Furthermore, the medial cells fired first, then the lateral cells fired succeedingly. These results suggest that the time domain of the motor coordination was regulated by the symmetrical firing pattern of the bilateral cerebellum Purkinje cell activity.
