Fig. 3. Mechanosensory stimuli were able to elicit novelty responses immediately after a prior discharge interruption. The three rows illustrate pairs of responses obtained when the stimulus (top trace) was given n electric organ discharges (EODs) after a pause (left traces; n=50, 100, 1000, top to bottom row) and 10 000 EODs later during steady firing (right traces). Stimulus timing is indicated by arrows. Pause durations were 7, 75 and 20 s (top to bottom).
