Measurements evaluating possible cerebral hemispheric asymmetries were taken by hand on frontal, parietal, and temporal cortex on 60 formalin-fixed Macaca mulatta and Macaca fascicularis brain specimens. No statistically significant (P less than 0.05) right/left side differences in the mean length of four sulci in visual-processing areas of the cortex were found. The sulcus adjacent to the region cytoarchitecturally homologous to the motor speech area in the human brain did not show pronounced asymmetry. In both species, however, a small parietal lobe sulcus showed greater development on the left hemisphere than in the right. In measurements made using digital planimetry, right/left side differences in the area of the dorsal cingulate gyrus were not found. Behavioral evidence suggests that monkeys do not exhibit a consistent pattern of cerebral dominance for functions associated with most of these regions of the brain.
对60个用福尔马林固定的恒河猴和食蟹猴脑标本的额叶、顶叶和颞叶皮质进行了手工测量，以评估可能存在的大脑半球不对称性。在皮质视觉处理区域的四条脑沟平均长度上，未发现具有统计学意义（P小于0.05）的左右侧差异。与人脑运动性语言区细胞结构同源区域相邻的脑沟未表现出明显的不对称性。然而，在这两个物种中，一个小的顶叶脑沟在左半球比右半球发育得更好。在使用数字平面测量法进行的测量中，未发现扣带回背侧区域面积的左右侧差异。行为证据表明，猴子在与大脑大部分这些区域相关的功能上，并未表现出一致的大脑优势模式。
