Baseline behavioral and pharmacokinetic measures for rats in the reduction group. Correlation coefficients between these measures and the Compensation Index are also shown.

Measure	Mean ± SEM (Range)	Compensation Index
Baseline behavior
Daily Infusion Rate	28.4 ± 1.3 (16.8 to 43.4)	r = −0.51**
Diurnal Index	0.41 ± 0.02 (0.14 to 0.56)	r = 0.20, p = 0.35
Pharmacokinetics
Volume of Distribution (l/kg)	3.4 ± 0.2 (1.9 to 5.4)	r = 0.23, p = 0.28
Clearance (l/h•kg)	1.8 ± 0.1 (0.8 to 3.5)	r = −0.11, p = 0.60
Half-Life (h)	1.5 ± 0.2 (0.7 to 3.8)	r = 0.28, p = 0.19

^**Significantly correlated, p < 0.01.
