Brainstem acoustic evoked potentials (BAEP) in patients with vertebral-basilar insufficiency and multiple sclerosis are analysed by means of cross correlation functions. By comparing BAEP recordings of the right and left side this method yields a quantitative and objective valuation of the symmetry of the electrical brainstem activity whereby the BAEP waveform is also considered. The diagnostic value of the cross correlation function is studied by demonstration of examples and comparison of the patient groups with normal subjects. The presented method of analysis is not an alternative to the usual interpretation of latencies and amplitudes. But it may be recommended as a supplementary criterion, because without any additional effort it provides further objective information which can be useful for the valuation of BAEP in some cases, especially if the potentials are not well discernible.
通过互相关函数分析椎基底动脉供血不足和多发性硬化症患者的脑干听觉诱发电位（BAEP）。通过比较左右两侧的BAEP记录，该方法可对脑干电活动的对称性进行定量和客观评估，同时也会考虑BAEP波形。通过实例展示以及将患者组与正常受试者进行比较，研究互相关函数的诊断价值。所提出的分析方法并非是对潜伏期和波幅常规解读的替代方法。但它可作为一项补充标准推荐使用，因为无需额外努力它就能提供更多客观信息，在某些情况下，这些信息对于评估BAEP可能是有用的，尤其是在电位难以清晰分辨时。
