(A) Mean ± SEM time spent on the grid floor for Grid+ (G+) and Grid− (G−) mice on the first preference test (Test 1). Chronic DCS pre-exposure had no effect on development of ethanol CPP after 2 CS+ and 2 CS− trials. (B) Mean ± SEM time spent on the grid floor for Grid+ (G+) and Grid− (G−) mice on the second preference test (after a total of 4 CS+ and 4 CS− trials). All groups show signficantly stronger CPP on Test 2 when compared to Test 1 (a significant Conditioning Subgroup × Test interaction), but there was no effect of DCS pre-exposure at any of the tested doses.
