摘要：

目的探讨布罗卡区(Broca’s area)与其他功能脑区的连接。方法研究192名正常人静息态下的功能磁共振数据,通过左右Broca与全脑体素的相关分析,研究Broca的功能连接,并通过统计分析比较左右Broca功能连接的差异。结果与Broca连接呈正相关的脑区有额中回、额下回,颞中回和缘上回;呈负相关的脑区有颞极颞中回,中央后回,顶叶,额内侧回,枕叶,且在同侧半球连接中,左侧Broca与额下回、Wernicke区连接强度大于右侧Broca与额下回、Wernicke右侧对应区连接,左侧Broca与背外侧前额叶皮层、前扣带回皮层和颞顶联合区等注意认知区及梭状回和舌回等视觉野部分区域连接小于右侧Broca连接。结论本研究发现Broca多功能相关及Broca与其他脑区功能连接的偏侧化存在的多样性,这将为大脑功能网络偏侧化研究奠定基础。
