The effect of handedness on the middle latency response of the auditory evoked potential was investigated by testing 16 right-handed and 16 left-handed young adults with normal hearing. Each handedness group contained eight males and eight females. Peaks PO, N(a),P(a),Nb,and Pb showed a progressive, statistically significant latency increase in left-handed subjects when compared with right-handed subjects. The latency difference was 1.1 ms at peak P(a) and 3.6 ms at peak Pb. There was no significant latency difference between males and females. Topographic brain mapping showed that the distribution of positivity of wave Pb was similar to the distribution for wave P(a) in both right- and left-handed subjects.
通过对16名听力正常的右利手和16名左利手年轻成年人进行测试，研究了利手对听觉诱发电位中潜伏期反应的影响。每个利手组包含8名男性和8名女性。与右利手受试者相比，左利手受试者的PO、N(a)、P(a)、Nb和Pb波峰的潜伏期呈逐渐增加且具有统计学意义。P(a)波峰的潜伏期差异为1.1毫秒，Pb波峰的潜伏期差异为3.6毫秒。男性和女性之间的潜伏期没有显著差异。脑地形图显示，右利手和左利手受试者中，Pb波的阳性分布与P(a)波的分布相似。
