Fig. 1From: Augmented fear bradycardia in rats with heart failureTop. Examples of confocal images of DHE fluorescence taken in the PAG of sham-operated (Sham) and congestive heart failure (CHF) rats. Scale bars: 50 μm. Bottom. Comparisons of DHE fluorescence intensities in the dorsolateral, lateral, and ventrolateral parts of the PAG (dlPAG, lPAG, and vlPAG) between 6 Sham and 6 CHF rats. Values represent mean ± SEM. *P < 0.05 vs. Sham rats, detected by two-sample t testsBack to article page
