中文摘要: 现代脑成像技术为我们开启了从未有过的机遇:科学家可以在0.5秒和3毫米的时空精度上观测活体人类大脑的全脑功能活动。这再一次唤起人们全面解读长期以来的神秘话题——“心脑关联”(Brain-Mind Association: BMA)的兴趣。近20年来静息态功能磁共振成像技术迅速发展,该话题已被初步探索并在心脑关联和脑功能发育研究方面取得了一些进展。本文概要介绍这些进展和与之密切相关的人脑功能连接组研究框架,类比人类全基因组关联方法,指出人脑功能连接组关联方法是深入研究脑功能与各种心理行为特质或疾病之间关系的关键方法学框架之一,阐述其目前面临的主要困难、解决方向和思路。人类全功能连接组关联研究需要世界各国科学家的联合并大力提倡发现科学和开放式科学文化。中国目前在一些方法学研究领域获得了良好的声誉,未来研究中各科研院所(特别是中科院)应加大力度培养多学科交叉人才,为人类心脑关联研究标准的制定和最终应用做出贡献。
Abstract:Modern brain imaging technology offers scientists an opportunity never happened before, at the temporal-spatial scale of 0.5 second and 3 millimeters, to tackle whole brain functional activity of the human brain in vivo. With no doubt, it calls us to revisit the ‘brain-mind association (BMA)’, an old but mysterious topic being for long time. Resting-state functional magnetic resonance imaging (R-fMRI) has developed rapidly since described in its seminal study nearly two decades ago. Recently, R-fMRI has been employed to explore the BMA and gained some findings. My task with this paper is to give a brief review on these initial explorations and to introduce the framework of human functional connectome. Similar to genome-wide association studies (GWAS), connectome-wide association studies (CWAS) was recommended as the key methodological framework on decoding the relationships between brain-mind and brain-disease, focusing on the relevant difficulties and solutions. The human brain CWAS request an international union of scientists from different countries to reach a successful discovery and open science. China has played a critical role of developing novel methodology for initial CWAS discovery. In future, research institutes and universities, especially, Chinese Academy of Sciences should strengthen various interdisciplinary research training programs and contribute to establishing an analytic and methodological standard of CWAS.
