Values are expressed as mean ± S.E.M. The “p (before-after)” column reflects differences between study days (intact vs. blocked) during the infusions (saline or trimethaphan)

*

p <0.05 for the comparison between baseline and infusion for each study day.

No significant differences were observed between study days at baseline.
