Maternal behaviors in rodents include a number of subcomponents, such as nursing, nest building, licking and grooming of pups, pup retrieval, and maternal aggression. Because each behavior involves a unique motor pattern, a unique ensemble neural circuitry must underlie each behavior. To what extent there is overlap in terms of brain regions and specific neurons for each circuit is being actively investigated. This review will first examine overlapping and separate components of pup retrieval and maternal aggression circuitries while examining a central role for medial preoptic area (MPA) in both behaviors. With an emphasis on experimental approaches, the review will then highlight recent findings and propose future directions for understanding maternal behavior regulation. Finally, examples for why studying the neural basis of maternal behaviors can bring insights to other areas of neuroscience, such as feeding, addiction, and anxiety and aggression regulation will be provided.
啮齿动物的母性行为包括许多子成分，如哺乳、筑巢、舔舐和梳理幼崽、找回幼崽以及母性攻击行为。由于每种行为都涉及独特的运动模式，每种行为背后必然存在独特的整体神经回路。目前正在积极研究每个回路在脑区和特定神经元方面的重叠程度。本综述将首先研究找回幼崽和母性攻击行为回路的重叠和独立成分，同时探讨内侧视前区（MPA）在这两种行为中的核心作用。在强调实验方法的基础上，本综述将突出近期的研究发现，并为理解母性行为调节提出未来的方向。最后，将提供一些例子，说明为什么研究母性行为的神经基础可以为神经科学的其他领域，如进食、成瘾、焦虑和攻击行为调节带来启示。
