The authors wish to note, "We used the term 'neuropeptide' in referring to the set of diverse neurochemicals that we examined in this study, some of which are not peptides; dopamine and serotonin are neurotransmitters and should be listed as such, and testosterone should be listed as a steroid. Our usage arose from our primary focus on the neuropeptides endorphin and oxytocin. Notwithstanding the biochemical differences between these neurochemicals, we note that these terminological issues have no implications for the significance of the findings reported in this paper.".
