Odor-guided behavior in mammals.

R L Doty

    Experientia
    |March 15, 1986
    PubMed
    Summary

    Animal experiences with odors profoundly influence behaviors like eating and mating, demonstrating complex links between olfaction, hormones, and experience. These odor-guided behaviors are intricate and not always directly caused by hormonal states.

    Area of Science:

    • Neuroscience
    • Ethology
    • Endocrinology

    Background:

    • Odor-guided behaviors are fundamental in many animal species.
    • Complex interactions exist between olfactory cues, hormonal states, and life experiences.

    Purpose of the Study:

    • To explore the intricate relationships between odor-guided behaviors, hormonal status, and experiential factors in animals.
    • To highlight the profound influence of early life odor experiences on later behaviors.

    Main Methods:

    • Review of existing literature on odor-guided behaviors in various species.
    • Analysis of studies examining the interplay of olfaction, hormones, and social/sexual experiences.

    Main Results:

    • Odor experiences significantly influence behaviors such as feeding, mating, fighting, and nesting.
    • Social encounters can rapidly alter behaviors and odor preferences in rats.
    • Hormonal factors can be overridden by social experience in odor-guided behaviors (e.g., urine marking in mice).
    • Olfactory input affects endocrine systems differently in sexually experienced versus inexperienced animals.

    Conclusions:

    • Odor-guided behaviors are complex, with multifaceted causal bases.
    • Simple causal relationships between hormones and odor-guided behaviors are not always evident.
    • Experience and social context play crucial roles in modulating odor-guided behaviors and their hormonal correlates.
