【摘要】：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.
[Abstract]:Self-confidence is an excellent personality quality of modern people, but also an important component of self-confidence enterprising.In order to study the neural origin of self-confidence, resting functional magnetic resonance imaging (fMRI) was used to explore the brain regions and brain networks related to self-confidence by using low-frequency amplitude and functional connection analysis of spontaneous neural activity in the brain.The results showed that the low frequency amplitudes of left middle temporal gyrus, right infratemporal gyrus and posterior central gyrus were closely related to self-confidence, and the connection strength between right inferior temporal gyrus and left precentral gyrus and right posterior central gyrus was positively correlated with self-confidence.The connection strength between this area and bilateral middle frontal gyrus, right superior frontal gyrus, left superior parietal lobule and left cingulate gyrus was negatively correlated with self-confidence, right posterior central gyrus and bilateral cerebral island, right middle temporal gyrus, left superior temporal gyrus, right posterior central gyrus, left superior temporal gyrus, and left superior temporal gyrus.The connection strength of left superior frontal gyrus was positively correlated with self-confidence, and negatively correlated with that of left anterior cuneate lobe.The connections between these regions of the brain and self-confidence suggest that the quality of self-confidence has a broad network basis of brain function, which provides new evidence for the study of self-confidence and related research.
