“…As one can clearly see, the quantity of consciousness of a state increases with the degree of phase locking in the local ZPF. The concomitant information gain in the ZPF, which causes a system to function as a whole, can be interpreted as integrated information, meaning that at this point the presented approach shares commonalities with the integrated information theory (IIT) of consciousness (Tononi, 2004(Tononi, , 2008(Tononi, , 2012Oizumi, Albantakis, & Tononi, 2014). However, in contrast to IIT, the expression for the quantity of consciousness given here relies on a universal mechanism and a theoretical framework that is on an equal footing with the fundamental theories of physics.…”

In this article, I present a novel approach to the scientific understanding of consciousness. It is based on the hypothesis that the full range of phenomenal qualities is built into the frequency spectrum of a ubiquitous background field and proceeds on the assumption that conscious systems employ a universal mechanism by means of which they are able to extract phenomenal nuances selectively from this field. I set forth that in the form of the zero-point field (ZPF) physics can offer a promising candidate that is qualified for playing the dual role as both the carrier of energy and consciousness. The appropriate mechanism, which rests upon the principle of dynamical coupling of ZPF modes, is a unique feature of quantum systems, suggesting that the dividing line between conscious and non-conscious systems is defined by the differentiation between quantum systems and classical systems. The presence of this mechanism in the brain is supported by the neurophysiological body of evidence, leading to a consistent explanation of the dynamical properties of the neural correlates of consciousness. Building on these findings, I lay the foundations for the conceptually coherent integration of consciousness into the physical worldview, derive an indicator for the quantity of consciousness of a given system, and outline the further steps toward a theory of consciousness.

“…[4] Fig 6: Definition of neural correlates of consciousness (NCC) [6] As depicted in the above figure, based on Tononi's review on evidences across lesion, stimulation and recording studies [6], Content-specific NCC (in red) directly contribute phenomenal distinctions (such as low level visual features, faces or places) to consciousness. The full NCC (in orange) is constituted by the union of all the content-specific NCC.…”

“…Dreams are a form of consciousness on this definition [4]. Consciousness only vanishes during dreamless sleep or under general anaesthesia when, from our own intrinsic perspective, everything disappears and we experience nothing [4]. Consciousness consists of all the states of feeling or sentience or awareness [9].…”

“…It is defined as a phenomenon which begins in the morning when we wake up from a dreamless sleep, and it goes on all day until we fall asleep or die or otherwise become unconscious [1,4] [Fig 1]. Dreams are a form of consciousness on this definition [4]. Consciousness only vanishes during dreamless sleep or under general anaesthesia when, from our own intrinsic perspective, everything disappears and we experience nothing [4].…”

ObjectiveAccording to a seminal hypothesis stated by Crick and Koch in 1995, one is not aware of neural activity in primary visual cortex (V1) because this region lacks reciprocal connections with prefrontal cortex (PFC).MethodsWe provide here a neuropsychological illustration of this hypothesis in a patient with a very rare form of cortical blindness: ventral and dorsal cortical pathways were lesioned bilaterally while V1 areas were partially preserved.ResultsVisual stimuli escaped conscious perception but still activated V1 regions that were functionally disconnected from PFC.InterpretationThese results are consistent with the hypothesis of a causal role of PFC in visual awareness.
