The Role of the Brain in Conscious Processes: A New Way of Looking at the Neural Correlates of Consciousness

Joachim Keppler
2018 Frontiers in Psychology  
In the introspective operating mode, which goes along with activations of the default mode network, the brain is receptive to the flow of ZPF information states that constitutes the record of conscious  ...  Instead, the brain taps into a wider spectrum of ZPF modes and, hence, gains access to an extended phenomenal color palette, resulting in expanded consciousness.  ...  SELF-REFERENTIAL CONSCIOUS PROCESSES Complementary to the extroverted, stimulus-oriented operating mode of the brain there is an introspective operating mode FIGURE 1 | Fundamental mechanism underlying  ...

Building Blocks for the Development of a Self-Consistent Electromagnetic Field Theory of Consciousness

Joachim Keppler
2021 Frontiers in Human Neuroscience  
In particular, resonant interaction with the ZPF is critical for understanding rapidly forming, long-range coherent activity patterns that are characteristic of brain dynamics.  ...  From this perspective, the brain is postulated to function as a resonant oscillator that couples to a specific range of ZPF modes, using these modes as a keyboard for the composition of an enormous variety  ...  From this perspective, the ZPF, which is accountable for the coordination of brain areas and the synchronization of brain activity, may be understood as the truly global workspace in which conscious processes  ...

The Dynamical Balance of the Brain at Rest

Gustavo Deco, Maurizio Corbetta
2010 The Neuroscientist  
Computational studies show that one of such dynamics, the anticorrelation between networks, depends on noise-driven transitions between different multistable cluster synchronization states.  ...  The authors review evidence that spontaneous, that is, not stimulus or task driven, activity in the brain at the level of large-scale neural systems is not noise, but orderly and organized in a series  ...  all the basic dynamical modes activated in a regular and balanced way.  ...
