    Neuropeptides regulate brain-gut functions, influencing gastrointestinal secretion, motility, and eating behavior. While brain control of the gut is increasingly understood, gut-to-brain communication pathways remain less explored.

    Area of Science:

    • Neuroscience
    • Gastroenterology
    • Endocrinology

    Background:

    • Neuropeptides function as neurotransmitters in both the brain and the gastrointestinal tract.
    • Anatomical studies show overlapping distributions of neuropeptides in the central nervous system (CNS) and the gut.
    • The functional interplay between the CNS and the gastrointestinal tract is not fully elucidated.

    Purpose of the Study:

    • To summarize CNS actions of neuropeptides on gastrointestinal functions.
    • To delineate efferent and afferent pathways in brain-gut communication.
    • To assess the progress in understanding brain-gut axis regulation.

    Main Methods:

    • Literature review and synthesis of existing research.
    • Analysis of studies on neuropeptide functions in the CNS and GI tract.

  • Examination of efferent and afferent neural pathways.

    • Main Results:

    • The CNS significantly influences gastrointestinal secretion, motility, blood flow, absorption, and eating behavior via neuropeptides.
    • Efferent pathways mediating brain-to-gut communication are increasingly understood.
    • Afferent pathways transmitting information from the gut to the brain are less well-characterized.

    Conclusions:

    • Significant advancements have been made in understanding how the brain regulates gastrointestinal functions over the last decade.
    • Knowledge regarding the afferent information flow from the gut to the brain requires further investigation.
