Abstract

Schizophrenia is a complex mental disorder with disorganized communication among large-scale brain networks, as demonstrated by impaired resting-state functional connectivity (rsFC). Individual rsFC studies, however, vary greatly in their methods and findings. We searched for consistent patterns of network dysfunction in schizophrenia by using a coordinate-based meta-analysis. Fifty-six seed-based voxel-wise rsFC datasets from 52 publications (2115 patients and 2297 healthy controls) were included in this meta-analysis. Then, coordinates of seed regions of interest (ROI) and between-group effects were extracted and coded. Seed ROIs were categorized into seed networks by their location within an a priori template. Multilevel kernel density analysis was used to identify brain networks in which schizophrenia was linked to hyper-connectivity or hypo-connectivity with each a priori network. Our results showed that schizophrenia was characterized by hypo-connectivity within the default network (DN, self-related thought), affective network (AN, emotion processing), ventral attention network (VAN, processing of salience), thalamus network (TN, gating information) and somatosensory network (SS, involved in sensory and auditory perception). Additionally, hypo-connectivity between the VAN and TN, VAN and DN, VAN and frontoparietal network (FN, external goal-directed regulation), FN and TN, and FN and DN were found in schizophrenia. Finally, the only instance of hyper-connectivity in schizophrenia was observed between the AN and VAN. Our meta-analysis motivates an empirical foundation for a disconnected large-scale brain networks model of schizophrenia in which the salience processing network (VAN) plays the core role, and its imbalanced communication with other functional networks may underlie the core difficulty of patients to differentiate self-representation (inner world) and environmental salience processing (outside world).

摘要

精神分裂症是一种复杂的精神障碍,其特征是大脑大规模网络之间的沟通紊乱,表现为静息态功能连接(rsFC)受损。然而,个体 rsFC 研究在方法和发现上存在很大差异。我们通过基于坐标的荟萃分析寻找精神分裂症网络功能障碍的一致模式。这项荟萃分析纳入了 52 篇文献中的 56 个基于种子的体素 rsFC 数据集(2115 名患者和 2297 名健康对照者)。然后,提取和编码了感兴趣区(ROI)的种子坐标和组间效应。种子 ROI 根据其在预先设定模板内的位置分为种子网络。多级核密度分析用于识别与每个先验网络相关的过度连接或连接不足的大脑网络。研究结果表明,精神分裂症的特征是默认网络(DN,自我相关思维)、情感网络(AN,情绪处理)、腹侧注意网络(VAN,突显处理)、丘脑网络(TN,信息门控)和躯体感觉网络(SS,参与感觉和听觉感知)内的连接不足。此外,还发现 VAN 与 TN、VAN 与 DN、VAN 与额顶网络(FN,外部目标导向调节)、FN 与 TN、FN 与 DN 之间的连接不足。最后,仅在精神分裂症中观察到 AN 与 VAN 之间的过度连接。我们的荟萃分析为精神分裂症离散的大规模脑网络模型提供了实证基础,其中突显处理网络(VAN)起着核心作用,其与其他功能网络的不平衡通信可能是患者区分自我表现(内在世界)和环境突显处理(外在世界)的核心困难的基础。
