In the last decades, the scientific study of consciousness in the scope of the cognitive neurosciences can be considered one of the greatest challenges of contemporary science. The Gerald Edelman theory of consciousness is one of the most promising and controversial perspectives. This theory stands out by its approach to topics usually rejected by other neurophysiologic theories of consciousness, as the case of the neurophysiologic explanation of qualia.
The goal of this paper is to review the dynamic core theory of consciousness, presenting the main features of the theory, analyzing the explanation strategies, their empirical extensions, and elaborating some critical considerations about the possibility of the neuroscientific study of qualia.
The central and additional theoretical components are analyzed, emphasizing its ontological, restrictive and explanatory assumptions. The properties of conscious phenomena and their cerebral correlates as advanced by the theory are described, and finally its experiments and empirical extensions are examined. The explanatory strategies of the theory are analyzed, based on conceptual isomorphism between the phenomenological properties and the neurophysiological and mathematical measures. Some criticisms could be raised about the limitations of the dynamic core theory, especially regarding its account of the so-called 'hard problem' of consciousness or qualia.
在过去几十年里,认知神经科学领域对意识的科学研究可被视为当代科学最重大的挑战之一。杰拉尔德·埃德尔曼的意识理论是最具前景且最具争议的观点之一。该理论因其对通常被其他意识神经生理学理论所摒弃的主题的探讨方式而脱颖而出,比如对感受质的神经生理学解释。
本文旨在回顾意识的动态核心理论,呈现该理论的主要特征,分析其解释策略、实证拓展,并阐述一些关于对感受质进行神经科学研究可能性的批判性思考。
分析了核心及其他理论成分,强调了其本体论、限制性和解释性假设。描述了该理论所提出的意识现象及其大脑相关物的属性,最后审视了其实验及实证拓展。基于现象学属性与神经生理学及数学测量之间的概念同构性,分析了该理论的解释策略。对于动态核心理论的局限性,尤其是在其对所谓意识的“难题”或感受质的阐释方面,可能会提出一些批评。
