Research in South Africa will complement the candidate's ongoing exploration of structure-function relations int he brain. The investigator proposes to extend his recent findings that systematically relate avian brain structure, across species and within species, to capacity for song learning. In these studies, associations between brain nucleus morphology and characteristics of song provide a novel approach to identifying nucleus function. The investigators will look for these associations across many bird species: across families, across species within a genus, and across individuals within a species. A unique focus will be to study the brains of females in which mate selection uses song perception. The investigators' current data demonstrate the power of this approach in Acrocephalus species that breed in eastern Europe, some of which migrate to subsaharan Africa. Access to Acrocephalus species with distinct song characteristics that breed in Africa is essential to extend the investigators' initial work on the song system. Work with these species will also allow them to apply this approach to another behavioral system, to take these studies to spatial memory in birds beyond the lab to a natural behavior. They will compare hippocampal anatomy in species that do and do not migrate. Finally, to complete any of these studies, they must establish phylogenetic relationships between species by analyses of mitochondrial DNA. All aspects of this work will involve close collaboration with experts in avian systematics at the Fitzpatrick Institute of African Ornithology, University of Cape Town, over the course of three visits, one (6 months) to identify study sites, work out molecular procedures, and begin taping males, and two later (3-month) visits during reproduction to record and catch additional species. Issues of motor and spatial learning, and of sex differences and individual health. Comparative study may give new insights in neural features associates with each.

在南非的研究将补充候选人正在进行的 探索大脑的结构-功能关系。 的 一位研究人员建议扩展他最近的发现， 将鸟类的大脑结构，跨物种和物种内， 学习歌曲的能力。 在这些研究中， 脑核团形态学和鸣唱的特点提供了一个新的 识别核功能的方法。调查人员会调查 对于许多鸟类物种之间的这种联系：跨家族，跨 一个属内的物种，以及一个物种内的个体。 一 一个独特的重点将是研究女性的大脑， 选择使用歌曲感知。 研究人员目前的数据 在Acrocephalus物种中证明了这种方法的力量， 在东欧繁殖，其中一些迁移到撒哈拉以南非洲。 获得Acrocephalus物种具有独特的歌曲特征， 在非洲繁殖对于扩大研究人员的初步工作至关重要 在歌曲系统上。 与这些物种合作也将使他们能够 将这种方法应用到另一种行为系统中， 鸟类的空间记忆在实验室之外变成了自然行为。 他们 将比较迁移和不迁移物种的海马体解剖结构。 最后，要完成这些研究，他们必须建立 通过线粒体分析物种之间的系统发育关系 DNA.这项工作的所有方面都将涉及与以下方面的密切合作： 非洲菲茨帕特里克研究所的鸟类系统学专家 开普敦大学鸟类学教授，在三次访问中， 一个月（6个月）确定研究地点，制定分子程序， 并开始拍摄男性，两个月后（3个月）的访问期间， 记录和捕捉更多的物种。 电机问题 和空间学习，以及性别差异和个人健康。 比较研究可能会给神经功能联想新的见解 每一个。
