The effect of removal of cerebrovascular sympathetic, parasympathetic or sensory nerve on brain cortical blood flow and spontaneous vasomotion during changes in systemic blood pressure was studied by laser-Doppler flowmetry in anaesthetized rats. Selective section of sympathetic fibres along the internal carotid artery markedly affected the ability to autoregulate, as measured in microvessels of the middle cerebral arterial territory. Removal of the parasympathetic nerves tended to reduce the ability to autoregulate, whereas no significant influence was found after sensory denervation. Following the denervations, spontaneous vasomotion was not significantly affected in frequency or amplitude.
通过激光多普勒血流仪在麻醉大鼠中研究了去除脑血管交感神经、副交感神经或感觉神经对全身血压变化期间脑皮质血流和自发性血管运动的影响。沿颈内动脉选择性切断交感神经纤维显著影响了自动调节能力，这在大脑中动脉区域的微血管中得到测量。去除副交感神经倾向于降低自动调节能力，而感觉神经去神经支配后未发现显著影响。去神经支配后，自发性血管运动的频率或幅度没有受到显著影响。
