Cocaine effects on entrances and explorations during CPP test

		Entrances		Explorations
		Saline-paired	Cocaine-paired	Saline-paired	Cocaine-paired
Male	Saline	94.2±7.8	83.3±6.8	69.9±7.3	71.2±2.9
	Cocaine	73.2±8.2	83.1±8.4	69.9±3.3	73.2±5.5
Female	Saline	93.0±11	113±11.7	72.8±5.5	64.5±3.7
	Cocaine	98.8±5.4	124.5±12.2*	61.9±3.6	84.6±3.5*

Data are shown as mean (±SEM) number of entrances and explorations while in the saline-paired and cocaine-paired chambers during CPP testing (n = 8–10 animals per group).

^*Indicates significant difference from saline-paired chamber at p < .05.
