Research Progress on Collaborative Multi-Neurotransmitter Networks in the Brain Reward System: Implications for Drug Addiction

Abstract

This article focuses on the research progress of the collaborative multi-neurotransmitter network in the brain reward system and its implications for drug addiction. Firstly, the basic concepts and key brain regions of the brain reward system were introduced, and its important roles in motivation, pleasure and reward perception were expounded. Then, the synergistic mechanism of various neurotransmitters such as dopamine, glutamic acid, gamma-aminobutyric acid, endogenous opioid peptides, and cannabinoids in the brain reward system was explored in detail, including their interrelationships in neural signal transmission, synaptic plasticity regulation, and rebound-related behavior regulation. Then, the changes of this collaborative multi-neurotransmitter network during the process of drug addiction were analyzed, such as imbalance in neurotransmitter release and alterations in receptor expression. Finally, the implications of these research advancements for the prevention, diagnosis and treatment strategies of drug addiction were discussed, aiming to provide a theoretical basis for further understanding the neurobiological mechanisms of drug addiction and developing more effective intervention methods.
