    In the following article, consciousness is described as the activation of different parts of the brain by the perception of the outside world making it a real and therefore interactive phenomenon. You can think of it as a sort of feedback loop between reality and mind, which dissolves their distinction. The brain, a part of reality, may be activated by the mysterious substance of consciousness and not just consciousness being the result of the activation of the brain. How consciousness shapes and influences brain activity may be the cause of the expansion of the pre-frontal cortex throughout evolution. How the brain came into existence must be understood by the mapping and understanding of the brain/ consciousness. Consciousness appears to be a fundamental property of everything. And so the ingredients that make up the human brain are no longer mysterious. See this thread by Magical Realist from September of last year. Another interesting theory was argued by analog57 or Russell Rierson in which he says that brains are a kind of tuning fork between the spiritual and physical realms. Where the brain is deemed as a transmitter over which thoughts are received and shared. And so the consciousness of reality plays a fundamental role in influencing not only the brain, but reality itself as a whole and in part.

    Network theory sheds new light on origins of consciousness

    The black dots correspond to the 264 areas of the cerebral cortex that the researchers probed, and the lines correspond to the increased strength of the functional connections between each of these brain areas when subjects consciously perceive the target. The "hotter" colors are associated with stronger connections. This figure illustrates that awareness of the target corresponds to widespread increase in the strength of functional connections (Marois / Godwin).

    Where in your brain do you exist? Is your awareness of the world around you and of yourself as an individual the result of specific, focused changes in your brain, or does that awareness come from a broad network of neural activity? How does your brain produce awareness?
    Vanderbilt University researchers took a significant step toward answering these longstanding questions with a recent brain imaging study, in which they discovered global changes in how brain areas communicate with one another during awareness. Their findings, which were published March 9 in the
    Proceedings of the National Academy of Sciences, challenge previous theories that hypothesized much more restricted changes were responsible for producing awareness.

    “Identifying the fingerprints of consciousness in humans would be a significant advancement for basic and medical research, let alone its philosophical implications on the underpinnings of the human experience,” said René Marois, professor and chair of psychology at Vanderbilt University and senior author of the study. “Many of the cognitive deficits observed in various neurological diseases may ultimately stem from changes in how information is communicated throughout the brain.”

    Using graph theory, a branch of mathematics concerned with explaining the interactive links between members of a complex network, such as social networks or flight routes, the researchers aimed to characterize how connections between the various parts of the brain were related to awareness.

    “With graph theory, one can ask questions about how efficiently the transportation networks in the United States and Europe are connected via transportation hubs like LaGuardia Airport in New York,” Douglass Godwin, graduate student and lead author on the research, said. “We can ask those same questions about brain networks and hubs of neural communication.”

    Modern theories of the neural basis of consciousness fall generally into two camps: focal and global. Focal theories contend there are specific areas of the brain that are critical for generating consciousness, while global theories argue consciousness arises from large-scale brain changes in activity. This study applied graph theory analysis to adjudicate between these theories.

    The researchers recruited 24 members of the university community to participate in a functional magnetic resonance imaging (fMRI) experiment. While in the fMRI scanner, participants were asked to detect a disk that was briefly flashed on a screen. In each trial, participants responded whether they were able to detect the target disk and how much confidence they had in their answer. Experimenters then compared the results of the high-confidence trials during which the target was detected to the trials when it was missed by participants. These were treated as “aware” and “unaware” trials, respectively.
    Comparison of aware and unaware trials using conventional fMRI analyses that assess the amplitude of brain activity showed a pattern of results typical of similar studies, with only a few areas of the brain showing more activity during detection of the target than when participants missed seeing it. The present study, however, was interested not simply in what regions might be more activated with awareness, but how they communicate with one another.


    Unlike the focal results seen using more conventional analysis methods, the results via this network approach pointed toward a different conclusion. No one area or network of areas of the brain stood out as particularly more connected during awareness of the target; the whole brain appeared to become functionally more connected following reports of awareness.

    Consciousness appears to break down the modularity of these networks“We know there are numerous brain networks that control distinct cognitive functions such as attention, language and control, with each node of a network densely interconnected with other nodes of the same network, but not with other networks,” Marois said. “Consciousness appears to break down the modularity of these networks, as we observed a broad increase in functional connectivity between these networks with awareness.”

    The research suggests that consciousness is likely a product of this widespread communication, and that we can only report things that we have seen once they are being represented in the brain in this manner. Thus, no one part of the brain is truly the “seat of the soul,” as René Descartes once wrote in a hypothesis about the pineal gland, but rather, consciousness appears to be an emergent property of how information that needs to be acted upon gets propagated throughout the brain.

    “We take for granted how unified our experience of the world is. We don’t experience separate visual and auditory worlds, it’s all integrated into a single conscious experience,” Godwin said. “This widespread cross-network communication makes sense as a mechanism by which consciousness gets integrated into that singular world.”

    Robert Barry, a research fellow in radiology and radiological sciences, was a co-author on the research. The research was funded by the National Institutes of Health (NIH) P30-EY008126 grant to the Vanderbilt Vision Research Center and NIH grant 5R01EB000461.

    Because consciousness is deeply rooted in reality and in order for brains to be activated consciousness is needed it seems.

    And what evidence* has lead you to that conclusion?

    (*As in evidence and not wishful thinking or misunderstanding.)

    That's nonsense.

    How would you know? Did you read the article? Consciousness comes about by brain activity and so consciousness can be equated to brain activity. How else did our pre-frontal cortex expand throughout evolution?

    Both of the two great revolutions in twentieth-century physics—Einstein’s Theories of Relativity and Quantum Theory—revealed that observation played an important role. - See more at:

    Which has nothing to do with the existence of the Universe.

    I'm sorry I misread your post.

    I meant that it's nonsense to say that consciousness is a property of everything.

    It seems that consciousness is the common denominator in the unification of reality. It links everything into one. It is the "one" thing that seems to exist and everything else is an appearance. See; http://www.gizmag.com/quantum-theory-reality-anu/37866/

    Sounds like simple New Age bullshit.

    But consciousness is only in your head. Don't mistake perception of reality for reality.

    The article you linked does not support your comments... At all.

    I am aware of this. But note that it does not contradict it either. The above comments are purely theoretical.

    Are you saying perceptions are unreal? That's rather dumb.

    Yes, perceptions aren't real.

    Most of the time our perceptions align with what is real, but not always. They are illusions generated by the brain. The brain often just makes shit up for us to perceive, especially when information is limited.

    You're talking about the binding problem and it's relationship to reality. We are perceiving reality. We observe, we relate, we arrange and finally we compute. Reality is absolute.

    We think we observe reality, but psychological experiments prove that perceptions often are not aligned with reality. And in fact, all animals have different senses and thus different perceptions. Are they living in a different reality?
