The dorsolateral visual area (DL) is one of a number of visual areas that have been defined by electrophysiological mapping procedures and cortical architecture in the extrastriate cortex of owl monkeys. The projections of DL were determined by the intra-axonal transport of 3H-proline, 3H-acetyl-wheat germ agglutinin, and horseradish peroxidase after cortical injections. The major ipsilateral projection of DL defined a new subdivision of the visual cortex in owl monkeys, the caudal inferior temporal cortex. Single injections in DL sometimes produced label in two separate regions in the caudal inferior temporal cortex, suggesting that functional subdivisions exist in this projection zone. Other targets of DL included the region of the frontal eye fields, the dorsomedial visual area, the dorsointermediate visual area (DI), a region of the cortex rostral to DI which we call the temporoparietal cortex, and possibly the ventral (V) and posterior parietal areas. A major feedback projection of DL was to V-II. Projections from DL to V-II and the dorsomedial visual area were roughly retinotopic. Projections from DL to the contralateral cerebral hemisphere were to DL and the inferior temporal cortex. Overall, the results support the concept that a major relay of visual information proceeds from V-I to V-II to DL and then to the inferior temporal cortex. In addition, similarities in connection patterns of DL in owl monkeys and V4 in macaque monkeys suggest that DL and much or all of V4 are homologous.
背外侧视觉区（DL）是通过电生理图谱程序和猫头鹰猴纹外皮层的皮质结构所定义的多个视觉区域之一。通过在皮质注射后进行³H-脯氨酸、³H-乙酰小麦胚凝集素和辣根过氧化物酶的轴突内运输来确定DL的投射。DL的主要同侧投射定义了猫头鹰猴视觉皮层的一个新亚区，即尾侧颞下皮层。在DL单次注射有时会在尾侧颞下皮层的两个不同区域产生标记，这表明在这个投射区域存在功能亚区。DL的其他靶点包括额叶眼区区域、背内侧视觉区、背中间视觉区（DI）、DI前方的一个皮质区域，我们称之为颞顶叶皮层，以及可能的腹侧（V）和后顶叶区域。DL的一个主要反馈投射是到V-II。从DL到V-II和背内侧视觉区的投射大致是视网膜拓扑的。从DL到对侧大脑半球的投射是到DL和颞下皮层。总体而言，结果支持这样一种概念，即视觉信息的主要中继从V-I到V-II再到DL，然后到颞下皮层。此外，猫头鹰猴的DL和猕猴的V4在连接模式上的相似性表明DL与V4的大部分或全部是同源的。
