(A) Mean grasp duration (seconds) elicited by a nutritive surrogate nipple as a function of prenatal treatment (water group, paired group, and long-delay group) when newborns were exposed to cineole odor before the test situation. Mean grasp durations correspond to the first and second half of the test (1–8 and 9–15 mins, respectively) (adapted from Ref. 125). (B) Mean grasp duration (seconds) to a nutritive surrogate nipple as a function of prenatal treatment (water group, paired group, and long-delay group). Neonates were pretreated with intragastric administrations of ethanol or water before being tested. Vertical lines represent the standard errors of the means. Asterisks denote significant differences between the paired group and the remaining prenatal treatments (A) and the significant difference existing between paired animals treated with ethanol before the test and the remaining control conditions (B).
