Mean number of cFos-like immunoreactivity in the PbN and NAcc

	PbN	NAcc
Sucrose	12.25 ± 1.08 (6.97 ± 1.08)*	5.21 ± 0.52 (0.63 ± 0.52)
EtOH	12.46 ± 1.89 (7.18 ± 1.89)*	5.28 ± 0.76 (0.7 ± 0.76)
Sucrose + EtOH	12.40 ± 1.65 (7.12 ± 1.65)*	4.09 ± 0.40 (-0.49 ± 0.40)
Distilled H2O	5.28 ± 0.62	4.58 ± 0.854

The numbers in the parenthesis indicate the mean of cFLI, after substracting the number of cFLI of DDW group from that of each stimulation group. ^*indicates that the mean number of each stimulus group is significantly different from that of DDW group (P<0.05).
