Abstract

As part of the developing body of research about neural correlates of higher cognitive functions and awareness we have recently reported that the creation of knowledge and meaning could be manifested via Cortical Singularities. In this work we present new neurophysiological evidence of the hypothesized cognitive cycle in the emergence of awareness when a presumable meaningful stimuli is presented to an animal. This stimulus is manifested in the neocortex, as the creation of the knowledge necessary for intentional behavior and decision making. The results are interpreted through the concept of Pragmatic Information, which is complementary to the Shannon Entropy Index. We identify large-scale synchronization across broad frequency band as potential manifestation of the `aha' effect, indicating the construction of knowledge and meaning from input sensory data and leading to awareness experience.

认知周期和意识出现的神经生理学证据
作为高级认知功能和意识的神经相关研究的一部分,我们最近报道了知识和意义的创造可以通过皮质奇点表现出来。在这项工作中,我们提出了新的神经生理学证据,证明当假设有意义的刺激呈现给动物时,意识出现的假设认知周期。这种刺激在新皮层中表现为有意识行为和决策所必需的知识的创造。结果通过语用信息的概念来解释,这是对香农熵指数的补充。我们将宽频带上的大规模同步识别为“啊哈”效应的潜在表现,表明从输入的感官数据构建知识和意义并导致意识体验。
