PHYSIOLOGICAL CORRELATES & NEURAL MECHANISMS OF THE INFANT CRY & VOCALIZATION

这个项目目前的重点是荷尔蒙、神经和 非人灵长类动物发声表达的药理学因素。 今年的主要发现包括： 1.原位杂交技术发现了rna特异性的证据。 绒猴部分组织中加压素和催产素的合成 下丘脑，证实了我们之前对这些神经肽的发现 免疫细胞化学。 2.幼年恒河猴的分离反应表现为 关于发声行为的动态过程，因为呼叫率 一个发声亚型的呼叫率随着时间的推移而下降，而 不同亚型在同一时间段内有所增加。

This project is currently focuses on the hormonal, neural, and pharmacological factors underlying vocal expression in nonhuman primates. Major findings this year include: 1. in situ hybridization techniques found evidence for RNA specific to the synthesis of vasopressin and oxytocin in parts of the marmoset hypothalamus, confirming our earlier finding on these neuropeptides using immuno-cytochemistry. 2. The separation response of infant rhesus macaques was shown to be a dynamic process with respect to vocal behavior, in that the calling rate of one vocal sub-type decreased over time, while the calling rate of a different subtype increased over the same time period.
