In the present paper it is argued that the "neural correlate of consciousness" (NCC) does not appear to be a separate "module" - but an aspect of information processing within the neural substrate of various cognitive processes. Consequently, NCC can only be addressed adequately within frameworks that model the general relationship between neural processes and mental states - and take into account the dynamic connectivity of the brain. We presently offer the REFGEN (general reorganization of elementary functions) model as such a framework. This model builds upon and expands the REF (reorganization of elementary functions) and REFCON (of elementary functions and consciousness) models. All three models integrate the relationship between the neural and mental layers of description via the construction of an intermediate level dealing with computational states. The importance of experience based organization of neural and cognitive processes is stressed. The models assume that the mechanisms of consciousness are in principle the same as the basic mechanisms of all aspects of cognition - when information is processed to a sufficiently "high level" it becomes available to conscious experience. The NCC is within the REFGEN model seen as aspects of the dynamic and experience driven reorganizations of the synaptic connectivity between the neurocognitive "building blocks" of the model - the elementary functions.
在本文中,有人认为“意识的神经关联物”(NCC)似乎不是一个单独的“模块”,而是各种认知过程的神经基质内信息处理的一个方面。因此,只有在对神经过程和心理状态之间的一般关系进行建模并考虑大脑动态连接性的框架内,才能充分探讨NCC。我们目前提供REFGEN(基本功能的一般重组)模型作为这样一个框架。该模型建立在REF(基本功能的重组)和REFCON(基本功能与意识)模型的基础上并进行了扩展。所有这三个模型都通过构建一个处理计算状态的中间层,整合了神经描述层和心理描述层之间的关系。强调了基于经验的神经和认知过程组织的重要性。这些模型假设,意识机制原则上与认知各方面的基本机制相同——当信息被处理到足够“高的水平”时,它就可供有意识体验使用。在REFGEN模型中,NCC被视为模型的神经认知“构建块”(基本功能)之间突触连接性的动态和经验驱动重组的各个方面。
