Set-up. A. Schematic illustrating the five paired lateral positions and the frontal position of the dipole-object (see inset). Distances from skin were varied between 1, 3, 5, 7, 10, 12 and 15 mm. B. Example for data extraction for the novelty response. The top shows EODs in response to four consecutive switches between a low resistance (shunt) and a high resistance as a raster plot. Following normalisation by the mean and variance (z-score), a significant acceleration of the EOD rate is apparent in the bottom plot (red dot). Responses were scored as significant if z-scores below -1.96 were achieved within 5 EODs after the switch (p < 0.05).
