KISS1 and Anxiety: We have recently shown the specificity of the MePD as a neural site for the role of kisspeptin in sexual behaviour, with micro‐infusion of kisspeptin into the MePD causing ex‐copula erections in male rats.21 On the other hand, little is known about the role of kisspeptin in the fear and anxiety response, although it was recently reported that habenula kisspeptin modulates fear in zebrafish.22 In rats, the role of kisspeptin on anxiety is controversial,23, 24 whereas it attenuated negative mood in humans.25
