Attenuation of Neophobia by Postweaning Individual Rearing in Mice

抄録

Thirty six male mice of CFW strain were housed in either isolated or grouped for sixty days after weaning, and were compared in an activity test, taste nephobia and taste aversion learning. The results showed that individual rearing appeared to attenuate neophbia to unexperienced tasting solution in mice. However, no effects of rearing condition were found in taste aversion learning. It is suggeted that isolation for a prolonged period after weaning produced less reactivitity to novel gustatory stimuli as well as to other environmental stimuli.
