To investigate parasympathetic influences on the forehead microvasculature, blood flow was monitored bilaterally in seven participants with a unilateral facial nerve lesion during conjunctival irritation with Schirmer's strips and while breathing at 0.15 Hz. Blood flow and slow-wave frequency increased on the intact side of the forehead during Schirmer's test but did not change on the denervated side. However, a 0.15 Hz vascular wave strengthened during paced breathing, particularly on the denervated side. These findings indicate that parasympathetic activity in the facial nerve increases forehead blood flow during minor conjunctival irritation, but may interfere with the 0.15 Hz vascular wave.
为了研究副交感神经对额头微血管的影响，在 7 名单侧面神经损伤的参与者中，在单侧 Schirmer 条刺激结膜和以 0.15Hz 频率呼吸时，对双侧的额部血流进行了监测。在 Schirmer 测试中，额部完整侧的血流量和慢波频率增加，但在去神经侧没有变化。然而，在有节奏的呼吸过程中，0.15Hz 的血管波增强，尤其是在去神经侧。这些发现表明，面神经中的副交感神经活动在轻微的结膜刺激时增加额部血流量，但可能干扰 0.15Hz 的血管波。
