Temporal aspects of the SOR. Latency of the novelty response and the Schnauzenorgan response obtained using high-speed video analysis with one fish (128 frames/s). For both responses data are presented with respect to the beginning of a response and with respect to the peak. A. Latency of the novelty response for on-responses (grey boxes) and off-responses (black boxes). B. Latency of the SORs with respect to the time of a change in dipole resistance. C. Latency of the SORs relative to the time of the first EOD following a change in the dipole-objects resistance. In all cases on- and off-responses were significantly different from each other (Mann-Whitney U-test: p < 0.01). A legend to the parameters displayed in A-C is shown at the right hand side of the figure.
