有关人类头皮脑电的完整信息可以在头皮上的电场分布及其随时间的变化中获得。在单极和双极电极组合之间记录的任何常规脑电都可以从场分布的完整数据中重建。然而，场分布记录的数据量很大，需要在评估之前进行大量的数据约简。数据简化的一种策略特别具有挑战性：有限数量的颅内模型生成器，如果可能的话，只有一个可以用来解释给定的场分布。因此，场分布的序列可以由模型生成器(S)的参数来描述，这些参数随时间变化。
Complete information about the human scalp EEG is available in the distribution of the electrical field on the scalp, and its change as a function of time. Any conventional EEG as recorded between unipolar and bipolar electrode combinations can be reconstructed from complete data of the field distributions. However, the large amount of data in recordings of field distributions demands considerable data reduction before evaluation. One strategy of data reduction is particularly challenging: a limited number of intracranial model generators, if possible only one, can be fitted to account for a given field distribution. A sequence of field distributions could thus be described by the parameters of the model generator(s) which change as a function of time.
