Fig. 9. (A) Cumulative distribution functions of scallop production near the
minimum lateral distance (MLD) for each stimulus type. Notice how the
distribution of Amp and LL scalloping is highly skewed, with more than 80% of
the fish scalloping zero times. The distribution of scallop production during
multimodal stimulation is normal (P>0.05). (B) The mean number of
scallops 1 s before and 2 s after the time of the object's minimum lateral
distance. Scallop production elicited from multimodal stimulation was
significantly greater than its component unimodal Tub stimulation. (C,D)
Unfiltered electric organ discharge (EOD) rates during 10 rotations of the
stimulus object. An example of an increase (5 vs 11) in scallop
production near the minimum object distance after the addition of LL
stimulation. *P<0.05, error bars equal ± 2
s.e.m. Tub, tuberous electrosense; Amp, ampullary electrosense; LL,
mechanosensory lateral line.
