性腺激素有助于大脑的性分化和整个生命过程中的行为,从最初的神经模式到成年神经回路的“激活”。性行为是研究荷尔蒙激活神经回路的机制的理想系统。性行为是一种受荷尔蒙调节的先天社会行为,存在于不同物种之间。虽然两性都在寻找并从事性行为,但交配中涉及的具体行为是性二态的。因此,男性和女性中介性动机和性行为的神经回路是重叠的,但又是不同的。此外,性行为在很大程度上依赖于两性的性腺激素循环。在阐明性腺激素如何调节性行为回路中的生理特性并对行为产生影响方面,最近取得了重大进展。因此,在这篇简短的综述中,我们回顾了男性和女性性动机和行为的神经回路,从最初对信息素的感觉检测到延伸的杏仁核,再到下丘脑内侧核和奖励系统。我们还讨论了性腺激素如何影响这些回路中每个节点的生理和功能。通过更好地了解性腺激素影响性行为回路的各种方式,我们可以对复杂行为的神经基础有更丰富、更完整的理解。
Gonadal hormones contribute to the sexual differentiation of brain and behavior throughout the lifespan, from initial neural patterning to “activation” of adult circuits. Sexual behavior is an ideal system in which to investigate the mechanisms underlying hormonal activation of neural circuits. Sexual behavior is a hormonally regulated, innate social behavior found across species. Although both sexes seek out and engage in sexual behavior, the specific actions involved in mating are sexually dimorphic. Thus, the neural circuits mediating sexual motivation and behavior in males and females are overlapping yet distinct. Furthermore, sexual behavior is strongly dependent on circulating gonadal hormones in both sexes. There has been significant recent progress on elucidating how gonadal hormones modulate physiological properties within sexual behavior circuits with consequences for behavior. Therefore, in this mini-review we review the neural circuits of male and female sexual motivation and behavior, from initial sensory detection of pheromones to the extended amygdala and on to medial hypothalamic nuclei and reward systems. We also discuss how gonadal hormones impact the physiology and functioning of each node within these circuits. By better understanding the myriad of ways in which gonadal hormones impact sexual behavior circuits, we can gain a richer and more complete appreciation for the neural substrates of complex behavior.
