Figure 2. Original recordings of responses evoked by the 40 Hz bursting pattern of sympathetic nerve stimulation during air breathing and systemic hypoxia in the absence and presence of the NPY antagonist BIBP 3226.

The periods of stimulation are indicated by bars under each response whilst the infusion of BIBP 3226 is indicated by the bar under the right panels. ABP, arterial blood pressure; FBF, femoral blood flow; FVR, femoral vascular resistance.
