In the owl monkey, microelectrode mapping of Brodmann's area 19 indicates that this region contains part or all of at least 5 separate representations of the visual field, each of which adjoins the anterior border of V II and collectively are termed the third tier of cortical visual areas (V I is the first tier; V II is the second tier). Described in detail in this report is one of the third tier areas which is located on the dorsal surface and the adjacent medial wall of the occipital lobe and corresponds to a densely myelinated zone of cortex. In this dorsomedial area (DM), the representation of the horizontal meridian is partially split, and thus, like V II (see ref. 4) and the dorsolateral crescent5, DM is a second order transformation of the visual hemifield. In one abnormal owl monkey, a portion of the upper quadrant was represented twice in DM. This abnormal case may provide some clues as to how the normal pattern of visuotopic organization is established in the developing brain.
在夜猴中，对布罗德曼19区的微电极图谱研究表明，该区域包含至少5个独立的视野表征的部分或全部，每个表征都毗邻V II的前边界，它们共同被称为第三层皮质视觉区（V I是第一层；V II是第二层）。本报告详细描述了位于枕叶背表面和相邻内侧壁上的第三层区域之一，它对应于皮质的一个髓鞘密集区。在这个背内侧区域（DM），水平子午线的表征部分分离，因此，与V II（见参考文献4）和背外侧月牙区5一样，DM是视觉半视野的二阶变换。在一只异常夜猴中，上象限的一部分在DM中被重复表征。这个异常案例可能为发育中的大脑中视觉拓扑组织的正常模式是如何建立的提供一些线索。
