Forehead blood flow was monitored in seven participants with a unilateral facial nerve lesion during relaxation, respiratory biofeedback and a sad documentary. Vascular waves at 0.1Hz strengthened during respiratory biofeedback, in tune with breathing cycles that also averaged 0.1Hz. In addition, a psychomotor rhythm at 0.15Hz was more prominent in vascular waveforms on the denervated than intact side of the forehead, both before and during relaxation and the sad documentary. These findings suggest that parasympathetic activity in the facial nerve interferes with the psychomotor rhythm in the forehead microvasculature.
在 7 名单侧面神经损伤的参与者中，监测到在放松、呼吸生物反馈和悲伤纪录片期间的额部血流。在呼吸生物反馈期间，血管波在 0.1Hz 处增强，与呼吸周期同步，平均为 0.1Hz。此外，在额部未受神经支配的一侧和完整的一侧，在放松和悲伤纪录片之前和期间，血管波形中的 0.15Hz 运动性节律更为明显。这些发现表明，面神经中的副交感神经活动干扰了额部微血管中的运动性节律。
