It has been known that olfactory stimuli increase the visual sensitivity in the fly and the fish. In flies, odorant caused flies both to increase aerodynamic power output and to steer straighter. In fish, visual motor response was increased upon presentation of amino acids as olfactory stimuli. In this study, we analyzed the increasing mechanism of visual motor response of the goldfish with measuring the optomotor response (OMR), edge triggering response (ETR) and electroretinogram (ERG). Before and after olfactory stimulation, we measured the OMR and the ETR. The goldfish's food solution and four amino acids (L‐alanine, L‐methionine, L‐arginine and L‐aspartic acid) were used for olfactory stimulation. The effect of amino acids on ERG at photopic level was determined before and after amino acid administration into one side of the fish's nostril. Olfactory stimulation by food solution increased the OMR up to about 20%. Olfactory stimulation by amino acids almost increased the OMR. ETR, the specific behavior observed in goldfish when it triggers the edge of a moving pattern, decreased by odorant. These results indicated that olfactory stimuli minimize the loss of tracking the moving pattern and thereby increasing the trailing distance without increasing swimming velocity. There were no products of ERG increasing by the odorant at photopic light level. Here we report that olfactory stimulation increased the motivation of visual perception to rotational motion and thereby diminishing the loss of tracking.
