In the second step, we further analyzed gender-related differences depending on the current smoking status of smokers and ex-smokers compared to non-smokers. PLoS Med 3: Female smokers and ex-smokers show higher activation in the bilateral superior frontal gyrus and ACC.

To investigate more specifically gender-related differences in an addicted population, we contrasted the smokers group with non-smokers.

In the second step, we further analyzed gender-related differences depending on the current smoking status of smokers and ex-smokers compared to non-smokers. No use, distribution or reproduction is permitted which does not comply with these terms. In fact the results of the analyses of craving are confounded by group attribution smokers already have higher craving. Therefore, we agree with the interpretation given by McClernon, suggesting that women and men engage different neural circuits in the processing of craving cues that lead ultimately to similar levels of subjective craving.
