Current mainstream theories of consciousness conduct research from single dimensions such as intracerebral module competition, somatic signal origins, neuronal cluster selection, and top-down executive control. They generally suffer from three limitations: hierarchical fracture, dimensional confusion, and narrow explanatory scope. Specifically, they lack a complete vertical emergence chain from cells to organs and then to the brain; fail to clearly distinguish between neural structural hierarchies and subjective experience levels; and cannot simultaneously explain three core mental phenomena—spontaneous emergence of thoughts, psychological internal friction, and empathic fusion—within a single framework. 本文通过整合全局工作空间理论、躯体标记假说、神经达尔文主义与前额叶执行功能理论,构建了多层级集群涌现-前额叶统合模型(MCE-PFC)。该模型提出:意识产生于“躯体集群内稳态信号涌现→潜意识神经集群竞争筛选→前额叶主意识统合”的三层级递进过程;所有念头与欲望的终极驱动源是躯体系统的内稳态偏差;结构层面前额叶与底层脑区存在永久的功能层级差异,体验层面二者可发生临时的神经同频共振,二者属于不同维度,互不矛盾。 By integrating Global Workspace Theory, Somatic Marker Hypothesis, Neural Darwinism, and Prefrontal Executive Function Theory, this paper constructs the Multi-level Cluster Emergence - Prefrontal Cortex Integration Model (MCE-PFC). The model proposes that consciousness arises from a three-stage progressive process: emergence of homeostatic signals from somatic clusters → competitive screening of subconscious neural clusters → integration of primary consciousness by the prefrontal cortex. The ultimate driving source of all thoughts and desires is the homeostatic deviation of the somatic system. At the structural level, there exists a permanent functional hierarchy between the prefrontal cortex and lower brain regions; at the experiential level, temporary neural synchronized resonance can occur between them. The two belong to different dimensions and are not mutually contradictory. 该模型用单一机制同时解释了正常意识运作、心理内耗、共情平静三类典型状态,弥补了现有理论的层级缺口与维度混淆问题,并提出5项可通过神经影像与行为实验验证的可证伪命题,为意识研究、临床心理干预、心智训练实践及认知因果学体系提供了统一的底层机制框架。 This model explains three typical states—normal conscious functioning, psychological internal friction, and empathic calm—with a single mechanism, addressing the hierarchical gaps and dimensional confusion in existing theories. It also puts forward five falsifiable propositions verifiable through neuroimaging and behavioral experiments, providing a unified underlying mechanistic framework for consciousness research, clinical psychological intervention, mental training practice, and the system of cognitive causality. 关键词:意识涌现;躯体标记;前额叶统合;集群竞争;内耗机制;认知因果学Keywords: consciousness emergence; somatic marker; prefrontal integration; cluster competition; internal friction mechanism; cognitive causality
