The Fractal Nature of the Brain: EEG Data Suggests That the Brain Functions as a “Quantum Computer” in 5-8 Dimensions
The brain has been traditionally viewed as a deterministic machine where certain inputs give rise to certain outputs. However, there is a growing body of work that suggests this is not the case. The high importance of initial inputs suggests that the brain may be working in the realms of chaos, with small changes in initial inputs leading to the production of strange attractors. This may also be reflected in the physical structure of the brain which may also be fractal. EEG data is a good place to look for the underlying patterns of chaos in the brain since it samples many millions of neurons simultaneously. Several studies have arrived at a fractal dimension of between 5 and 8 for human EEG data. This suggests that the brain operates in a higher dimension than the 4 of traditional space-time. These extra dimensions suggest that quantum gravity may play a role in generating consciousness.

Hard not to get worked up over the speculative possibilities. Consciousness as simultaneously an expression of and difference with whatever the fuck phusis is…

"It has been suggested that nature could be discrete in the sense that the underlying state space of a physical system has only a finite number of pure states. Here we present a strong physical argument for the quantum theoretical property that every state space has infinitely many pure states. We propose a simple physical postulate that dictates that the only possible discrete theory is classical theory. More specifically, we postulate that no information gain implies no disturbance or, read in the contrapositive, that disturbance leads to some form of information gain…"

Consider the famous Schrodinger’s cat paradox, a thought experiment in which a cat in a box simultaneously exists in two states (this is known as a ‘quantum superposition’). According to quantum theory it is possible that the cat is both dead and alive – until, that is, the cat’s state of health is ‘measured’ by opening the box.
When the box is opened, allowing the health of the cat to be measured, the superposition collapses and the cat ends up definitively dead or alive. The measurement has disturbed the cat.This is a property of quantum systems in general. Perform a measurement for which you can’t know the outcome in advance, and the system changes to match the outcome you get. What happens if you look a second time? The researchers assume the system is not evolving in time or affected by any outside influence, which means the quantum state stays collapsed. You would then expect the second measurement to yield the same result as the first. After all, “If you look into the box and find a dead cat, you don’t expect to look again later and find the cat has been resurrected,” says Stephanie. “You could say we’ve formalised the principle of accepting the facts”, says Stephanie.Corsin and Stephanie show that this principle rules out various theories of nature. They note particularly that a class of theories they call ‘discrete’ are incompatible with the principle. These theories hold that quantum particles can take up only a finite number of states, rather than choose from an infinite, continuous range of possibilities. The possibility of such a discrete ‘state space’ has been linked to quantum gravitational theories proposing similar discreteness in spacetime, where the fabric of the universe is made up of tiny brick-like elements rather than being a smooth, continuous sheet.As is often the case in research, Corsin and Stephanie reached this point having set out to solve an entirely different problem altogether… >continue<

A Quantum Theory of Mitt RomneyJeff Javerbaum&#160;&#187;

"&#8230; the Romney candidacy represents literally a quantum leap forward. It is governed by rules that are bizarre and appear to go against everyday experience and common sense. To be honest, even people like Mr. Fehrnstrom who are experts in Mitt Romney’s reality, or “Romneality,” seem bewildered by its implications; and any person who tells you he or she truly “understands” Mitt Romney is either lying or a corporation.   &gt;continue&lt;

Quantum physics explanation for smell gains traction

The means by which a detected molecule is translated into a smell within the brain has already been the subject of Nobel prize-winning research&#8230;

Most recently, Dr Turin published a paper showing that flies can distinguish between molecules that are chemically similar but in which a heavier version of hydrogen had been substituted.
Like a spring with a heavier weight at one end, the vibration frequency is lowered, and flies appear to notice.
"There&#8217;s still lots to understand, but the idea that it cannot possibly be right is no longer tenable really," said Andrew Horsfield of Imperial College London.



Somewhere I am remembering the claim that of all sensory experience, the olfactory is the only type that bypasses hermeneutical mediation.  If that&#8217;s true, one wonders about a connexion.  Yet intuition itself says there&#8217;s something spooky wild about scent.
