    Summary

    Neurotransmitter research has advanced our understanding of behavior, linking brain chemicals to normal and abnormal states. Studies in animals and humans explore these neurochemical substrates and the impact of toxicants like lead.

    Area of Science:

    • Neuroscience
    • Behavioral Science
    • Psychopharmacology

    Background:

    • Significant advancements in understanding brain neurotransmitters and their role in behavior over the past decade.
    • Development of hypotheses on neurochemical substrates of behavior based on animal studies and pharmacological agents.
    • Application of these findings to human studies for explaining normal and abnormal behavior states.

    Purpose of the Study:

    • To provide a comprehensive overview of the progress in neurotransmitter research related to behavior.
    • To review principles of brain neurotransmitter function and interactions.
    • To introduce neurotransmitter-related hypotheses in psychiatry and neurology and discuss the impact of toxicants.

    Main Methods:

    • Review of experimental observations in animals using specific pharmacological agents.
    • Integration of findings from basic laboratory investigations and clinical studies in humans.
    • Discussion of toxicants' effects on behavior via neurotransmitter alteration, using lead intoxication as an example.

    Main Results:

    • Established numerous neurotransmitter-related hypotheses for normal and abnormal behavior.
    • Demonstrated the link between brain chemistry and behavioral states.
    • Highlighted the influence of environmental factors, such as lead exposure, on neurotransmitter function and behavior.

    Conclusions:

    • Neurotransmitter research is crucial for understanding behavior and developing treatments for psychiatric and neurologic disorders.
    • Further investigation is needed to validate current hypotheses and explore the full spectrum of neurotransmitter involvement in behavior.
    • Toxicants can significantly impact behavior by altering brain neurotransmitter systems, necessitating further research into these interactions.
