| 摘 要： | 目的 探讨首发精神分裂症患者听觉门控异常与脑功能异常激活之间的关系.方法 11例首发精神分裂症患者及11名年龄、性别、受教育程度相匹配的正常对照进行脑功能磁共振成像,实验采用多声音刺激和单声音刺激比较的范式,以多声音刺激减单声音刺激的对比探测感觉门控的脑激活效应.以SPM2处理脑影像数据,使用两样本t检验比较两组间听觉感觉门控脑功能激活的差异.结果 患者组的感觉门控脑激活在右侧海马(x ＝ 24,y ＝ -28,z ＝ -8,体素集合数＝ 16)、右侧丘脑(x ＝ 8,y ＝ -4,z ＝ 4,体素集合数＝ 22)低于正常对照组(t ＝ 3.57,P ＝ 0.001;t ＝ 3.38,P ＝ 0.001).结论 首发精神分裂症患者的听觉门控异常可能与海马、丘脑等脑区的功能激活异常有关.

| Abstract: | Objective The present study was conducted to explore the correlation of sensory gating deficits with abnormal brain activation in the first episodic schizophrenia.Methods Eleven schizophrenia patients in the first episodic and 11 healthy controls matched in gender,age,education underwent a fMRI auditory sensory gating task.The experiments were performed using multi-and single click stimulation and the brain activation of sensory gating effects was measured usingmulti-clicks minus single click.The results we... |
