Figure 5


Fig. 5. Novelty responses elicited by electrosensory stimuli. (A,B) Mean ± s.d. (N=10) of the inter-EOD (electric organ discharge) interval normalized to basal EOD interval (upper dashed line=100%), plotted as a function of time. The arrows indicate the moment when two wires are short circuited in front of the fovea. (A) Biphasic larvae exhibit larger and longer-lasting accelerations than (B) juveniles and adults in response to changes in reafferent signals. (C) The amplitude of the novelty response (defined as the maximum shortening of the inter-EOD interval as a percentage of the basal interval) decreases with fish length. (D) The half relaxation time (defined as the time in which the interval returns to values equal to basal minus 50% of the amplitude of the response) also decreases with fish length.
