Regarding the article “Estrous cycle and sex affect cocaine-induced behavioural changes in CD1 mice” by M. Martini, A. Xavier Pinto and O. Valverde, published in Psychopharmacology 231: 2647 (2014), the authors regret having used several sentences in the Introduction section from another publication without specific attribution. In particular, the Van Swearingen et al. (2013b) reference, included in the Reference section, should be added to the end of the following sentences: “Women are more sensitive...” and “These observed sex differences ...” in the first paragraph; “Females work harder for psychostimulants...” and “These observations have made the rat...” in the second paragraph; and ”Psychostimulants like cocaine...” and “Psychostimulants elicit both enhanced locomotion...” in the third paragraph. Two additional citations were omitted in the third paragraph: Kelly et al., (1975), and Kuhn et al., (2010). The authors apologize for these errors of omission.
