ABSTRACT
Objective To observe the effects of electrical stimulation of the cerebellum′s fastigial nucleus on neurogenic autonomic functional disturbances in rats after ischemic stroke. Methods Right middle cerebral artery occlusions (MCAOs) were performed on rats and their heart rate variability (HRV) was analysed. The MCAO rats were randomly divided into a group whose cerebellar fastigial nuclei (FNS) were stimulated and a control group. The power spectrum components and chaos of their heart rate variability were analysed. The MCAOs were performed after two cerebellar fastigial nuclei had been destroyed by pretreatment with ibotenic acid (IBO), to investigate the effect of stimulating the cerebellum′s fastigial nucleus on heart rate variability. Results The power spectral components and chaos in the heart rate variability of the MCAO rats were reduced, and there was a significant difference in the effectiveness rate compared with the sham groups (P
