利用顺行示踪剂菜豆白细胞凝集素（PHA-L）研究了从TEO区到TE区的连接组织。在TEO的外侧部分进行单次或在一个卡斯中进行两次少量的示踪剂注射。标记的终端被发现在TE的限制区域内的2至5个致密病灶。在这些病灶中，终末分布在中间层之外，形成垂直于皮质表面延伸的柱状簇。这种连接的特异性可能来自于一个组织，这是功能特异性，而不是retinotopic.Single轴突重建的柱状病灶表现出不均匀的层状分布的功能。有的轴突的主干位于浅层，有的轴突的主干位于中层。
The organization of connections from area TEO to TE was studied by the use of the anterograde tracer Phaseolus vulgaris leucoagglutinin (PHA-L). Single or, in one cass, two small injections of the tracer were made in the lateral part of TEO. Labeled terminals were found in restricted regions of TE within two to five dense foci. In these foci, terminals were distributed beyond the middle layers to form a columnar cluster elongated vertical to the cortical surface. This specificity of connections may derive from an organization that is feature specific rather than retinotopic.Single axons reconstructed from the columnar foci showed heterogeneous features in the laminar distribution. Arbors of some axons were localized in the superficial layers, and those of other were in the middle layers.
