Magnetic responses to the five events. A ~ C, data from a representative subject. A), top view traces of all the sensors. B), enlarged waveforms of selected sensors indicated by circles in A, C), root sum square (RSS) waveforms obtained from selected pair gradiometers. D, grand-averaged RSS waveforms of the five events. The lower trace indicates the results (p value) of the one-way repeated measures ANOVA at all sampling points, which evaluates whether the RSS value differs significantly among events.
