研究目的:

本研究旨在通过多模态脑成像(fMRI/EEG)与肠道菌群分析技术,深入探讨吸烟对精神分裂症患者奖赏加工与吸烟线索反应神经机制的调节作用,揭示其“自我治疗”背后的脑-肠轴交互机制,为发展针对共病的个性化干预策略提供科学依据。  

Objectives of Study:

This study aims to utilize multimodal neuroimaging (fMRI/EEG) and gut microbiome analysis to investigate how smoking modulates the neural mechanisms of reward processing and smoking cue reactivity in patients with schizophrenia, to uncover the brain-gut axis interactions underlying the "self-medication" behavior, and to provide a scientific basis for developing personalized intervention strategies for this comorbidity.
