| 摘 要： | 目的:研究正常儿童优势眼视觉诱发电位特征。方法:对47名正常儿童进行全视野刺激多导视觉诱发电位研究。结果:优势眼视觉诱发电位以0_z电极为代表,P_(100)潜伏期较非优势眼缩短(P<0.01),而N_(75)—P_(100)峰峰值较非优势眼增大(P<0.05)。结论:中枢神经系统存在偏利现象,这种偏利现象可能与控制视神经髓鞘优先形成的某种遗传机制有关,或是中枢神经系统突触的局部构造、突触效能的差异。

| Abstract: | Objective:to study character of VEPs on dominant eye in normal children.Method:Multiple channel pattern reversal visual evoked potentials were recorded full field stimuli in 47 normal children.Results;The P100 latency from dominant eye was shorter than that from non-dominant eye.Conclusion:There was lateralization in the central nervous system.The lateralization may be a reflection of differences in the topological organization of the synapses or in synaptic efficacy. |
