Figure 1. Original recordings of responses in N rats evoked by a bursting pattern (40 Hz) of sympathetic nerve stimulation during air breathing throughout, before and after l-NAME and during SNP infusion to restore baseline FVR to pre-l-NAME value.

The period of stimulation is indicated by the bars. ABP, arterial blood pressure; FBF, femoral blood flow; FVR, femoral vascular resistance.
