为了确定猴屏状体中投射到视觉区域 V4 的细胞是否与投射到其他视觉区域的细胞位于同一区域，我们向两只猴子的 V4 区注射了逆行荧光示踪剂二脒黄。在一只动物的 PM 区域（位于月前回 V4 区域内侧的区域）还注射了第二种示踪剂（固蓝）。 V4 区注射标记腹侧屏状细胞的前后范围约 5-6 毫米。更内侧的月前注射标记了邻近背侧和更外侧屏状体的细胞。这些结果与其他研究的数据一起表明，猴子和猫一样，屏状核中有一个“视觉”区域，与多个视觉区域（包括 V1、V2、V4、MT、FST、MST、TEO 和 TE）相互连接。数据还表明，该区域的背侧和外侧是另一个区域，与不同的视觉区域相连，包括后顶叶皮层的几个区域。
In order to determine whether the cells in the monkey claustrum which project to visual area V4 are found in the same territory as cells projecting to other visual areas, we made injections of the retrograde fluorescent tracer diamidino yellow into area V4 in two monkeys. Injections of a second tracer, fast blue, were also made in area PM, an area just medial to area V4 on the prelunate gyrus, in one animal. Area V4 injections labeled cells in ventral claustrum over about 5-6 mm of its anterior-posterior extent. The more medial prelunate injection labeled cells in adjacent dorsal and more lateral claustrum. These results, together with data from other studies, suggest that in the monkey, as in the cat, there is a ''visual'' region of claustrum that is interconnected with multiple visual areas including V1, V2, V4, MT, FST, MST, TEO and TE. The data also suggest that dorsal and lateral to this region is another zone which is connected with different visual areas, including several in posterior parietal cortex.
