Theoretical approaches to understanding consciousness have begun to converge upon areas of general agreement, yet substantive differences remain. Here, I introduce a new theoretical framework for the emergence of consciousness from the functional integration of the thalamocortical system: the Temporally-Integrated Causality Landscape (TICL). TICL presents a novel perspective which addresses important phenomenological characteristics of consciousness that other frameworks, such as IIT, do not. First, the TICL is based upon the observation that conscious experiences are temporally continuous, not discrete. Secondly, the TICL establishes a thalamocortical basis for the point-of-view. According to TICL, consciousness is composed of contents that arise from neuronal subsystems that have meaning from the point-of-view of the larger, integrated system in which they are nested. Meaningful contents emerge from the subsystems because they exhibit a level of temporally-integrated causality (TIC) that is distinguishable from that of the larger system.
理解意识的理论方法已经开始在一些共识领域汇聚,但实质性的分歧仍然存在。在这里,我引入了一个新的理论框架,用于从丘脑皮质系统的功能整合中产生意识:时间整合因果关系景观(TICL)。TICL 提出了一个新的视角,解决了其他框架(如 IIT)没有解决的意识的重要现象学特征。首先,TICL 基于这样一种观察,即意识体验是时间连续的,而不是离散的。其次,TICL 为观点建立了一个丘脑皮质基础。根据 TICL,意识由源自神经元子系统的内容组成,这些内容从嵌套在其中的更大、整合系统的角度来看具有意义。有意义的内容从子系统中出现,是因为它们表现出一种可与更大系统区分开来的时间整合因果关系(TIC)水平。
