Fig. 2. Mean ± SEM % place preference to 1.0 g/kg ethanol expressed as [time in ethanol context/(time in ethanol context + time in Saline Context)].
Upper panel shows % preference for male (n = 19) and female (n = 17) rats, respectively. Lower panel shows % preference for all rats (N = 36). *P < 0.05 relative to no preference at 50% as determined by one-tailed t-tests. +P = 0.054.
