Where is the consciousness located? Cosmic Consciousness? I recently became aware of questions regarding the location of consciousness. The argument put forward is that the consciousness is separate to the body. This is not something I considered before. 

The first is conjecture by a Doctor Fenwick https://www.psychologytoday.com/intl/blog/think-well/201906/does-consciousness-exist-outside-the-brain

"Hence, in Fenwick’s view, the brain does not create or produce consciousness; rather, it filters it. As odd as this idea might seem at first, there are some analogies that bring the concept into sharper focus. For example, the eye filters and interprets only a very small sliver of the electromagnetic spectrum and the ear registers only a narrow range of sonic frequencies. Similarly, according to Fenwick, the brain filters and perceives only a tiny part of the cosmos’ intrinsic “consciousness.”
Fenwick is not a physicist, so I dredged the following link, the mind of wigners friend which supports the Fenwicks theory.

The second is based on quantum mechanics https://www.jstor.org/stable/23040667?read-now=1&amp;seq=1
The key points central to the article are

"A. My body with its internal nervous system(explored to any future degree of physiological completeness) functions as a pure mechanism according to the laws of nature. Further more quantum mechanics is the ultimate basis of the mechanism.

B. I am aware that by incontrovertible direct evidence of knowledge (information) entering my consciousness."

The 3rd is offered as evidence of the first 2 links https://youtu.be/Uq8l4XVfgPA

Am I correct in thinking if all the information in the universe exists in a timeless dimension(membrane) of space and our brains only access a part of it, making us who we are. Can we access more information towards enlightenment maybe? or sixth senses? via meditation a bit like the Buddha may have done?

In particular can any one point out if there are any errors in the second link that might make its central argument incorrect?
It is never a good idea to mix the speculations of the modern rationalists with buddhism. In buddhism, the location of consciousness is irrelevant. The thing to know about consciousness is this:


  "He discerns consciousness, the origination of consciousness, the
  cessation of consciousness, the path of practice leading to the
  cessation of consciousness. He discerns the allure of consciousness,
  the drawback of consciousness, and the escape from consciousness.
  
  "And what is consciousness? These six classes of consciousness:
  eye-consciousness, ear-consciousness, nose-consciousness,
  tongue-consciousness, body-consciousness, intellect-consciousness.
  This is called consciousness. From the origination of name-&amp;-form
  comes the origination of consciousness. From the cessation of
  name-&amp;-form comes the cessation of consciousness. And just this noble
  eightfold path is the path of practice leading to the cessation of
  consciousness, i.e., right view, right resolve, right speech, right
  action, right livelihood, right effort, right mindfulness, right
  concentration. The fact that pleasure &amp; happiness arises in dependence
  on consciousness: that is the allure of consciousness. The fact that
  consciousness is inconstant, stressful, subject to change: that is the
  drawback of consciousness. The subduing of desire &amp; passion for
  consciousness, the abandoning of desire &amp; passion for consciousness:
  that is the escape from consciousness.
  
  "For any brahmans or contemplatives who by directly knowing
  consciousness in this way, directly knowing the origination of
  consciousness in this way, directly knowing the cessation of
  consciousness in this way, directly knowing the path of practice
  leading to the cessation of consciousness in this way, directly
  knowing the allure of consciousness in this way, directly knowing the
  drawback of consciousness in this way, directly knowing the escape
  from consciousness in this way, are practicing for disenchantment —
  dispassion — cessation with regard to consciousness, they are
  practicing rightly. Those who are practicing rightly are firmly based
  in this doctrine &amp; discipline. And any brahmans or contemplatives who
  by directly knowing consciousness in this way, directly knowing the
  origination of consciousness in this way, directly knowing the
  cessation of consciousness in this way, directly knowing the path of
  practice leading to the cessation of consciousness in this way,
  directly knowing the allure of consciousness in this way, directly
  knowing the drawback of consciousness in this way, directly knowing
  the escape from consciousness in this way, are — from disenchantment,
  dispassion, cessation, lack of clinging/sustenance with regard to
  consciousness — released, they are well-released. Those who are
  well-released are fully accomplished. And with those who are fully
  accomplished, there is no cycle for the sake of describing them.
