Abstract

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 0.1. Hz strengthened during respiratory biofeedback, in tune with breathing cycles that also averaged 0.1. Hz. In addition, a psychomotor rhythm at 0.15. Hz 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.
