胎儿对口服液体化学溶液表现出行为反应，包括整体活性的增加和物种典型动作模式的产生，面部擦拭。在妊娠第20天的大鼠胚胎中进行了一系列实验，将具有强烈嗅觉特征的化合物——柠檬醛和环己酮以气相给予。胎儿对液相和气相的刺激表现出相似的行为反应，这表明产前化学感觉信息的处理有共同的基础。气相化学感觉刺激足以引发大鼠胎儿的行为激活和刻板动作模式，这种模式预测了出生后的嗅觉导向行为。这些结果表明，通常发生在水介质中的产前化学感觉体验可能与由空气嗅觉线索指导的产后行为的发展有关。
Fetuses exhibit behavioral responses to intraoral infusions of chemical solutions presented in liquid phase, including an increase in overall activity and the production of a species-typical action pattern, facial wiping. A series of experiments were conducted in which chemical compounds with strong olfactory characteristics—citral and cyclohexanone—were presented in gas phase to rat fetuses on day 20 of gestation. Fetuses exhibited similar behavioral responses to stimuli presented in liquid and gas phases, suggesting a common basis for the processing of prenatal chemosensory information. Chemosensory stimuli in gas phase are sufficient to elicit both behavioral activation and a stereotypic action pattern of the rat fetus, patterns that anticipate postnatal olfactory-directed behavior. These results suggest that prenatal chemosensory experience, which normallay occurs in an aqueous medium, may be relevant to the development of postnatal behavior that is directed by airborne olfactory cues.
