This paper investigates the compatibility between the theoretical framework of the global neuronal workspace theory (GNWT) of conscious processing and the perturbational complexity index (PCI). Even if it has been introduced within the framework of a concurrent theory (i.e. Integrated Information Theory), PCI appears, in principle, compatible with the main tenet of GNWT, which is a conscious process that depends on a long-range connection between different cortical regions, more specifically on the amplification, global propagation, and integration of brain signals. Notwithstanding this basic compatibility, a number of limited compatibilities and apparent differences emerge. This paper starts from the description of brain complexity, a notion that is crucial for PCI, to then summary of the main features of PCI and the main tenets of GNWT. Against this background, the text explores the compatibility between PCI and GNWT. It concludes that GNWT and PCI are fundamentally compatible, even though there are some partial disagreements and some points to further examine.
本文研究了意识加工的全局神经元工作空间理论（GNWT）的理论框架与微扰复杂性指数（PCI）之间的兼容性。即使PCI是在一种并行理论（即整合信息理论）的框架内提出的，但原则上它似乎与GNWT的主要宗旨兼容，GNWT认为意识过程依赖于不同皮质区域之间的长程连接，更具体地说，依赖于脑信号的放大、全局传播和整合。尽管存在这种基本兼容性，但仍出现了一些有限的兼容性和明显的差异。本文首先描述了对PCI至关重要的大脑复杂性概念，然后总结了PCI的主要特征和GNWT的主要宗旨。在此背景下，本文探讨了PCI与GNWT之间的兼容性。结论是，尽管存在一些部分分歧和一些有待进一步研究的问题，但GNWT和PCI在根本上是兼容的。
