人脑内癫痫组织的局部阵发性放电（可以在脑电图中以电压尖峰的形式记录）也会产生颅外磁场。通过最近开发的神经磁测量技术对这些磁场进行了评估。焦点区域磁尖峰场强的表面测量似乎足以确定阵发性放电背后的电流的位置、深度、方向和极性。
Local paroxysmal discharges of epileptic tissue within the human brain, which may be electrically recorded as voltage spikes in the EEG, also generate extracranial magnetic fields. These fields were assessed by means of recently developed neuromagnetometric techniques. Surface measurements of magnetic spike field strength in the region of the focus appear sufficient to establish the location, depth, orientation and polarity of currents underlying the paroxysmal discharge.
