拇指屈伸运动诱发的脑电位的变化

观察各运动变量对拇指屈伸运动诱发脑电位的影响。当拇指运动时施以一定的抗屈负荷，随负荷的增加，脑电位中的Ｎ１波发生趋于提前；Ｎ２波与运动时的峰速度呈正相关；而且Ｐ２、Ｎ３波的发生则分别与屈曲运动的完成和伸张运动的起始有关。     

广义相关时延估计方法在神经系统损伤检测中的应用

应用广义相关时间延迟估计方法，经由诱发电位潜伏期变化的测定，分析研究了撞击加速度和缺窒息实验条件下中枢时间系统的损伤问题。计算机模拟和诱发电位信号分析表明，当神经系统发生损伤时，诱发电位的潜伏期会出现显的变化，这种化可以由广义相关时间延迟估计方法而有效测定。

与音、象有关的pop

Pop是一个与生活密切相关的词。现实生活中强劲的pop倾向，使pop的生命力愈来愈强，新的表达，新的意义也随之愈来愈多。本文从听觉、形象、视觉思维的角度来谈与音、象有关的pop；试从形、声、象、意兼备的且具有不凡构词能力的pop中看思维在词汇形成的过程中所起的积极作用。     

音乐与驾驶心理

人的心理状态会因外界环境的刺激而受到影响，而受到影响的过程首先是感官感知的过程，这种感知包括视觉、听觉、触觉等等。音乐直接作用于人的听觉，从而对其驾驶行为和心理起到影响作用。     

Value of acoustic perceptual method for analysis of compensatory articulation errors in postoperative patients with cleft palate

Objective To establish an acoustic perceptual method analyzing the compensatory articulation errors in children with operated cleft palate via the formants of Chinese pure vowels. Methods The first three formants which represent vocal transmission character in Chinese pure vowels of 84 subjects with operated cleft palate, were measured by Computerized Speech Signal Processing System （CSSPS）. The Chinese vowel graph of postoperative patients with cleft palate was stated by the first formant frequencies （F1） and the second formant frequencies （F2） of the Chinese pure vowels between the two groups. Results Values of F1 and F2 of vowels except [a] in the poor articulation group （Group A） were significantly different from those in the good articulation group （Group B） （P〈0.05 or P〈 0.01）. As compared with that in Group B, the vowel graph demonstrated the decreased perceptual distances in Group A. These findings indicated that there might still be the backward movements of tongue, perverted mandibular movements and disharmonious lip movements in addition to the velopharyngeal insufficiency （VPI） in Group A. Conclusion The speech articulation of children with repaired cleft palate should be gained by correcting the aberrant compensatory articulation errors in the condition of velopharyngeal competence. Computerized Speech Signal Processing System （CSSPS）, which is regarded us the content of objective quantitative measurement, is a precise, simple, reliable and atroumatic technique for children with cleft palate to analyze pathological compensatory articulation errors.     

多发性硬化患者MRI、CT和诱发电位的对比分析

报告３２例多发性硬化（ｍｕｌｔｉｐｌｅｓｃｌｅｒｏｓｉｓ，ＭＳ）患者ＭＲＩ、ＣＴ和诱发电位的对比结果。各项检查中以ＭＲＩ异常率最高（８４．３％）。３项诱发电位（ＶＥＰ、ＢＡＥＰ、ＳＥＰ）检查的异常率虽低于ＭＲＩ，但３项检查中至少１项异常的异常率为８１．２５％，ＣＴ仅为４２．３％。认为ＭＲＩ与诱发电位结合应用可有效地为ＭＳ提供早期诊断。
