Behavioral responses toward maternal odor and acetophenone odor in developing rat pups. Y-maze tests show the number of choices toward odors during five trials (±S.E.M.) for PN7, PN14, and PN23 pups (A). Odor choices were determined in separate tests consisting of maternal odor versus familiar odor (clean bedding) or acetophenone versus. familiar odor. (B) The nipple attachment test shows latency to attach to the nipple (±S.E.M.) by PN14 and PN23 pups exposed to a lactating female with maternal odor removed (“no odor”), or with presentation of maternal odor or acetophenone in an airstream above the mother’s ventrum. *p < 0.050 and ***p < 0.001. A total of 94 pups were used, with N = 7–8/group.
