The application of a source derivation technique to topographic mapping of the pattern-reversal visual evoked potential is described. Comparisons were made with non-cephalic and common average reference recordings. Source derivation yielded wave forms which were less influenced by activity of reference origin. Source derivation wave forms were similar to those obtained with common average referencing but contour plots showed less spread of regions of maximal activity in the case of source derivation. It is suggested that source derivation may be useful in further studies of the topography and sources of cerebral evoked potentials.
本文描述了一种源推导技术在图形翻转视觉诱发电位地形图绘制中的应用。将其与非头部参考记录和公共平均参考记录进行了比较。源推导产生的波形受参考源活动的影响较小。源推导波形与公共平均参考法获得的波形相似，但等高线图显示，在源推导的情况下，最大活动区域的扩散较小。有人提出，源推导可能有助于进一步研究脑诱发电位的地形图和来源。
