Parental behavior denotes a vareity of genetically programmed activities in which parents help their young to survive to maturity. A highly successful research has been devoted to the psychoneuroendocrine bases of parenting in two species, rat and sheep. As a result empirical data along with conceptual formulations have been obtained which provide a model for generating hypothesis for the study of other species. This review was written to draw the attention to this research because of its enormous potential significance for problems pertaining to human infant care. It discusses the current status of research on the physiological bases of parental behavior, 相似文献

阿尔茨海默病是一种起病隐匿,进行性发展的神经系统退行性疾病。临床上以记忆障碍、失语、失用、失认、视空间损害、执行功能障碍以及人格和行为改变等全面性痴呆表现为特征,病因迄今未明,发病机制复杂。本文对可能的发病机制:遗传因素(包括ApoE基因、早老素-1和早老素-2基因,APP基因、α2巨球蛋白基因、TOMM40基因、COL25A1基因);Aβ代谢(合成、分解、转运);神经递质学说;自由基与氧化应激学说;金属离子学说等进行综述。 相似文献

精神、心理因素会引起神经递质的改变,神经递质的变化又能引起促性腺激素的分泌异常,以神经递质作为桥梁,研究精神、心理因素与多囊卵巢综合征(PCOS)的关系。精神、心理因素使体内多巴胺、去甲肾上腺素、β-内啡肽及5-羟色胺的含量变化,从而影响促性腺激素释放激素及黄体生成素的水平。因此,精神、心理因素是PCOS的重要诱因,而PCOS又加重心理障碍。 相似文献
