Objective. We aimed at characterizing, in non-invasive human brain recordings, the large-scale, coordinated activation of distant brain regions thought to occur during conscious perception. This process is termed ignition in the Global Workspace Theory, and integration in Integrated Information Theory, which are two of the major theories of consciousness. Approach. Here, we provide evidence for this process in humans by combining a magnetically-induced phosphene perception task with electroencephalography. Functional cortical networks were identified and characterized using graph theory to quantify the impact of conscious perception on local (segregation) and distant (integration) processing. Main results. Conscious phosphene perception activated frequency-specific networks, each associated with a specific spatial scale of information processing. Integration increased within an alpha-band functional network, while changes in segregation occurred in the beta...

用磁磷探测有意识的感知电路。

目的。我们的目标是在无创人类大脑记录中表征被认为在有意识感知期间发生的远距离大脑区域的大规模协调激活。这个过程在全球工作空间理论中被称为“点燃”，在综合信息理论中被称为“集成”，这是意识的两个主要理论。方法。在这里，我们通过将磁感应的phosph感知任务与脑电图相结合，为人类的这一过程提供了证据。使用图论对功能性皮层网络进行识别和表征，以量化意识对局部（隔离）和远距离（整合）处理的影响。主要结果。有意识的磷光感知可激活特定于频率的网络，每个网络都与信息处理的特定空间范围相关。
