自信是现代人优秀的个性品质,也是自信进取性的重要构成要素.为研究自信的神经起源,采用静息态功能磁共振成像技术,以大脑自发神经活动的低频振幅、功能连接分析来探究与自信相关的脑区及脑网络.结果发现:左侧颞中回、右侧颞下回和中央后回的低频振幅值与自信有紧密关系;右侧颞下回与左侧中央前回和右侧中央后回之间的连接强度与自信正相关,该脑区与双侧额中回、右侧额上回、左侧顶上小叶和左侧扣带回之间的连接强度与自信负相关;右侧中央后回与双侧脑岛、右侧颞中回、左侧颞上回、左侧额上回的连接强度与自信正相关,与左侧楔前叶的连接强度和自信负相关.这些大脑区域连接与自信的关系表明自信品质具有广泛的脑功能网络基础,为自信及相关研究提供了新证据.
Self-confidence is the outstanding personality quality of modern people, but also an important component of self-confidence aggressive.In order to study the neural origin of self-confidence, rest state-function magnetic resonance imaging technology, low frequency amplitude of brain spontaneous activity, functional connectivity analysis to explore and Confidence-related brain regions and brain network.The results showed that: the left temporal gyrus, right inferior temporal gyrus and central posterior gyration of low frequency amplitude and confidence have a close relationship; the right inferior temporal gyrus and the left central anterior and right The strength of the connection between the central back and back is positively correlated with self-confidence. The connection between the brain area and bilateral middle frontal gyrus, right upper frontal gyrus, left superior parietal lobule and left cingulate gyre is negatively correlated with self-confidence; Right posterior central back and bilateral insula, right middle temporal gyrus, left temporal superior gyrus, left superior sum superior posterior connection strength and self-confidence are positively correlated, and the left wedge anterior lobe connection strength and confidence negatively correlated. The connections between these brain regions and self-confidence indicate that the quality of self-confidence has a broad network of brain functions that provide new evidence of confidence and research.
