In utero taste/odor aversion conditioning in the rat.
Rat fetuses exposed to a taste-odor stimulus and an aversive stimulus in utero showed an aversion to the taste/odor stimulus when tested 16 days postnatally. Fetuses which received various control treatments in utero did not show an aversion. These data show that rat fetuses at 20 days of gestation are capable of associative learning which can be demonstrated more than two weeks postnatally.
