Patterns of cortical connections were studied in brain sections cut parallel to the surface of mechanically flattened cortex after single, double, or multiple injections of wheatgerm agglutinin conjugated to horseradish peroxidase (WGA-HRP) in area 17 of galagos (Galago crassicaudatus). Intrinsic connections of area 17 included a systematic pattern of patches of labeled cells and terminations associated with blobs of high cytochrome oxidase activity. The patches of connections extended with decreasing density for a distance of 2 mm or more from the margins of injection sites. Injections also revealed dense interconnections with area 18 (V-II) and the middle temporal visual area (MT). Single injections in area 17 produced several foci of label in both area 18 and MT, suggesting that a given location in area 17 is interconnected with subsets of processing modules in both of these fields. Injections including dorsolateral area 17 also labeled cortex between area 18 and MT. Finally, most injections in area in the temporal lobe.
在粗尾婴猴（Galago crassicaudatus）的17区单次、双次或多次注射与辣根过氧化物酶结合的麦胚凝集素（WGA-HRP）后，对平行于机械压平的皮质表面切割的脑切片中的皮质连接模式进行了研究。17区的内在连接包括与高细胞色素氧化酶活性的斑片相关的标记细胞和终末的系统性斑片模式。连接斑片从注射部位边缘以逐渐降低的密度延伸2毫米或更长距离。注射还显示出与18区（V-II）和颞中视觉区（MT）的密集相互连接。在17区的单次注射在18区和MT区都产生了几个标记灶，这表明17区的给定位置与这两个区域中的处理模块子集相互连接。包括背外侧17区的注射也标记了18区和MT区之间的皮质。最后，颞叶区域的大多数注射。
