论文摘要
意识的物理基础是当代科学旨在解决的最有趣的开放问题之一。通过将大脑作为交互信息系统接近，复杂的网络理论极大地有助于了解不同心态的大脑过程。我们通过比较在两个不同条件下的个体的静息状态功能性脑网络来研究非平常的心理状态：摄入迷幻酿造啤酒ayahuasca之前和之后。为了量化大脑区域连接性之间的功能性，统计对称性，我们计算功能性脑网络的成对信息均衡。与大多数在本地或全球范围内完成的通常网络量化不同，信息奇偶校验量化了考虑整个网络结构的成对统计相似性。我们发现在迷幻影响下，在个体的大脑网络上的平均信息奇偶校验的增加。值得注意的是，在迷幻影响下，所有个体的边缘系统和额叶皮层之间的信息均等始终更高。
The physical basis of consciousness is one of the most intriguing open questions that contemporary science aims to solve. By approaching the brain as an interactive information system, complex network theory has greatly contributed to understand brain process in different states of mind. We study an non-ordinary state of mind by comparing resting-state functional brain networks of individuals in two different conditions: before and after the ingestion of the psychedelic brew Ayahuasca. In order to quantify the functional, statistical symmetries between brain region connectivity, we calculate the pairwise information parity of the functional brain networks. Unlike most of usual network quantification, which is done on a local or global scale, information parity quantifies the pairwise statistical similarities considering the entire network structure. We detect an increase in the average information parity on brain networks of individuals under psychedelic influences. Notably, the information parity between regions from the limbic system and frontal cortex is consistently higher for all the individuals while under the psychedelic influence.
