Changes in mean arterial blood pressure and heart rate during CS+ and CS− in saline (S) infused rats (n=7) vs. angiotensin-II (Ang-II) infused rats (n=7)

	CS+				CS−
	ΔmBP (mm Hg)		ΔHR (bpm)		ΔmBP (mm Hg)		ΔHR (bpm)
	S	Ang-II	S	Ang-II	S	Ang-II	S	Ang-II
pk C1	+6.3± 3.2	+5.7± 3.3	+5.2 ±3.8	+11.2 ±6.4	+5.2± 2.0	+4.1± 2.3	+8.1± 3.3	+11.6 ±6.5
avg C2	+1.7± 2.4	+2.4± 2.1	−4.2± 5.5	−13.2± 8.9*	+0.3± 0.8	+0.6± 1.3	−3.1± 3.5	−4.1± 5.6
post- shock	6.5± 4.0	−4.0± 6.2*	+26 ±24	+18 ±8	N/A	N/A	N/A	N/A

See Figure 1 for definitions of pk C₁, avg C₂ and post-shock. No shock was delivered post-CS−, so a value is inappropriate. The values shown in Table 1 may differ from those read directly from Figure 1 because the individual rat’s changes in mBP or in HR, particularly for pkC₁, were attained at somewhat different times after tone onset across rats.
