Sex differences in the morphology of neural and peripheral structures related to reproduction often parallel the frequency of particular behaviours displayed by males and females. In a variety of model organisms, these sex differences are organized in development by gonadal steroids, which also act in adulthood to modulate behavioural expression and in some cases to generate parallel anatomical changes on a seasonal basis. Data collected from diverse species, however, suggest that changes in hormone availability are not sufficient to explain sex and seasonal differences in structure and function. This paper pulls together some of this literature from songbirds and lizards and considers the information in the broader context of taking a comparative approach to investigating genetic mechanisms associated with behavioural neuroendocrinology.
与生殖相关的神经和外周结构形态上的性别差异,通常与雄性和雌性表现出的特定行为频率相似。在多种模式生物中,这些性别差异在发育过程中由性腺类固醇组织形成,性腺类固醇在成年期也发挥作用,调节行为表达,在某些情况下还会在季节性基础上产生平行的解剖学变化。然而,从不同物种收集的数据表明,激素可利用性的变化不足以解释结构和功能上的性别及季节性差异。本文汇总了一些来自鸣禽和蜥蜴的相关文献,并在采用比较方法研究与行为神经内分泌学相关的遗传机制这一更广泛背景下考虑这些信息。
