颞叶癫痫发作间期的脑电图痫样放电与磁场有关。在头部的球形部分记录的磁尖峰的最大值看起来相当对称，而在下颞区记录的磁尖峰的最大值通常具有不规则的形状。此外，它们的大小通常不相等，下颞区的极值通常比上颞区的极值的大小低。这种形状和大小上的不对称可能是由于颅骨在颞区上的非球形，或者是由于中间组织的电导率的变化。我们提出了我们的观察，在两个病人表明，头部的表面轮廓有助于明显的不对称的领域模式，但头部轮廓本身可能无法解释的不对称性，在临床数据中看到的。
EEG interictal epileptiform discharges in temporal lobe epilepsy are associated with magnetic fields. The maxima of magnetic spikes recorded over the spherical portions of the head appear fairly symmetric, whereas those over the lower temporal region often have irregular shapes. Furthermore, their magnitude is often unequal with the extremum over the lower temporal region usually of lower magnitude than the extremum over the upper temporal region. This lack of symmetry in shape and magnitude may be due to non-sphericity of the skull over the temporal region or to variations in conductivities of intervening tissues. We present our observation in two patients suggesting that the surface contours of the head contribute to the apparent asymmetries of the field pattern but that the head contours alone may not account for the asymmetries seen in the clinical data.
