If the elements were oriented in opposite directions, the waveform of the fiber on the right (1) would be upright (or positive) since its depolarization vector is directed towards the recording lead. The contribution of the fiber on the left (2) would be inverted (or negative) since its depolarization vector is directed away from the recording lead. However, the amplitude of waveform 2 will be less than that of waveform 1 since the recording electrode is further away from the fiber on the left. The signal recorded when the fibers are simultaneously recorded will be the resultant or sum of these vectors as determined by the parallelogram.
