Fyn-deficient mice produced by inserting the beta-galactosidase gene (lacZ) into the fyn gene locus were tested in a radial maze, an open field and an elevated plus-maze. In the radial maze, the homozygous Fyn-deficient (fynz/fynz) mice showed no impairment in spatial learning, although they showed a stronger avoidance tendency for those arms located closer to the experimenter during pretraining (adaptation). In the open-field test, the fynz/fynz mice defecated more frequently in the bright condition than did the +/fynz mice, and they were less active during the first 10-min test period than the +/fynz mice. In addition, the temporal pattern of locomotor activity for fynz/fynz mice was altered by changing the illumination while the pattern for +/fynz mice remained relatively unchanged. Scores reflecting the fear-response in the elevated plus-maze were higher in the fynz/fynz mice. These results indicate that Fyn deficiency increased fear-response, but did not impair spatial learning in the radial maze. It is suggested that we should take account of effects of emotional factors in the learning experiment using mutant mice.
