... solely of myelinated electrosensory axons and shows both ontogenetic and sexual dimorphism. In particular, females exhibit a greater abundance of electrosensory axons, which may result in improved sensitivity of the electrosensory system and may facilitate mate identification for reproduction. Also...

...Katharine L. Campi; Chelsea E. Jameson; Brian C. Trainor Sex differences in behavior and morphology are usually assumed to be stronger in polygynous species compared to monogamous species. A few brain structures have been identified as sexually dimorphic in polygynous rodent species, but it is less...

...Jeroen B. Smaers; Poppy I. Mulvaney; Christophe Soligo; Karl Zilles; Katrin Amunts Social selective pressures are commonly considered as the main driving force of primate brain evolution. Primate social behaviour is, however, known to be sexually dimorphic, and no previous study has made a direct...

The pattern of development of these sex differences varies in different brain regions, suggesting that the mechanisms of estradiol regulation of neural development may also vary. The magnitude of sexual dimorphism in the neural song system varies across species...
