研究了狗的大脑和身体大小之间的异速关系以及大脑半球重量的不对称性。脑与体重的回归分析显示，根据幂函数Y = kXa，存在异速生长关系。研究发现，大脑右半球明显比左半球重。这一发现与爪子偏好无关。根据先前的研究，人们得出结论，大脑半球重量的右偏不对称可能是哺乳动物大脑的共同特征。结果的功能含义讨论了关于右半球专门化。
The allometric relationship between brain and body size and asymmetry in the weight of the cerebral hemispheres were studied in dogs. A regression analysis of the brain versus body weight revealed an allometric relationship according to the power function Y = kXa. The right cerebral hemisphere was found to be significantly heavier than the left. This finding was not associated with paw preference. In accordance with previous studies, it was concluded that the right-biased asymmetry in the weight of the cerebral hemispheres may be a common feature of the mammalian brain. Functional implications of the results were discussed with regard to the right hemisphere specializations.
