Abstract

The levels of soluble aminopeptidase (AP) activity were measured in the right and left frontal (FC), parietotemporal (PTC) and occipital (OC) cortex of male albino rat brains. The results showed more AP activity in the left cortex than in the right. Analyzing these results further, we found that the differences are significant for frontal cortex but not for parietotemporal nor occipital cortex. However, 76% of the rats were left-predominant for AP activity in the 3 cortical areas studied.

摘要

在雄性白化大鼠大脑的右、左额叶（FC）、顶颞叶（PTC）和枕叶（OC）皮质中测量了可溶性氨肽酶（AP）活性水平。结果显示，左侧皮质中的AP活性高于右侧。进一步分析这些结果，我们发现额叶皮质的差异具有显著性，但顶颞叶皮质和枕叶皮质的差异不显著。然而，在所研究的3个皮质区域中，76%的大鼠AP活性以左侧为主。
