中文摘要：
释放在功能的大脑成像研究经常被遇到了。然而，释放还没在数字处理期间被报导。在这研究，功能的磁性的回声成像(fMRI ) 被采用在数字增加任务期间在 15 个健康题目的大脑调查释放的模式。在几个大脑区域分析揭示重要释放，包括 posteriorcingulate， precuneus，前面的 cingulate 和前额的外皮。特别，我们在双边的 insula 发现了著名释放。为参予一个 combinated 方法的这些区域的认知功能的财务，我们在在有意识的休息期间支撑大脑活动讨论他们的贡献说，并且显示 insula 是从外部世界收集听觉的信息的一个重要区域。
英文摘要：
Deactivation has been encountered frequently in functional brain imaging researches. However, the deactivations during the numerical processing have not been reported yet. In this study, the functional magnetic resonance imaging （fMRI） was employed to investigate the pattern of the deactivation in the brain of 15 healthy subjects during the numerical addition task. Analyses revealed significant deacti- vations in several brain regions, including the posterior cingulate, precuneus, anterior cingulate and prefrontal cortex. Especially, we found notable deactivation in bilateral insula. Accounting for the cognitive functions of these regions participating in a combinated way, we discuss their contributions in sustaining the brain activity during conscious resting state, and indicate that the insula is an important area of gathering auditory information from the external world.
