It's a cool idea, but what?

Quote:
First, there is little agreement among scientists about exactly what information is. Second, when scientists refer to information they are often actually talking about the way energetic activity is organised in physical systems. Third, brain imaging techniques such as fMRI, PET and EEG don’t detect information in the brain, but changes in energy distribution and consumption.

Brains, I argue, are not squishy digital computers – there is no information in a neuron. Brains are delicate organic instruments that turn energy from the world and the body into useful work that enables us to survive. Brains process energy, not information.
Gonads.

That's like saying when I examine my computer all I can detect is heat, fans, air movement and a couple of lights, all of which is energy. Computers are therefore not actually computers.

The rest of the articles references some sense but pulls it together into an incoherent acid trip.

Yeah, it's difficult to make sense of the freestyling word salad in that Frontiers article otherwise.

Quote:
Something it is like-ness is not in itself sufficient for consciousness. Rather it is to recognize that:

(i) energy, forces, and work are actualized,

(ii) they are expressions of difference, and

(iii) there is something it is like, intrinsically, to undergo actualized difference.

I use the term actualized difference to refer to the active, antagonistic nature of energy, forces and work in a way that encompasses Heraclitean cosmology, Aristotelian energeia, and contemporary scientific descriptions of energy.
Don't take it too seriously and instead appreciate it for its aesthetic value. He's an art professor after all.

I have started looking at a couple of the links from Prof Interdisciplinary's meandering article. Because Science and Nature.

What is consciousness, and could machines have it? | Science

Integrated information theory: from consciousness to its physical substrate | Nature Reviews Neuroscience

They are much longer, have more references, and (to a first impression) are much more rigorous. Going to take me some time...

The only two things in the article (the Alternet one) that make sense are that 1. feedback is involved in some way and 2. for consciousness to exist whatever processing is going on has to be realized in a certain physical way. The rest is the author being confused about what energy means and turning it into his own idiosyncratic mush.

Quote:
The human brain consumes some 20% of the body’s total energy budget, despite accounting for only 2% of its mass. The brain is expensive to run. Most of the cost is incurred by neurons firing bursts of energetic difference in unthinkably complex patterns of synchrony and diversity across convoluted neural pathways.
No. Neurons don't fire energy anywhere. That's not how they work. In an electrical cable that is used to transmit a signal, there is real energy flux along the way. In a nerve it's more like a chain of dominoes falling, except one piece takes energy away from the next one. The little energy that actually travels along the axon actually travels backwards. What counts is the signal, the information, contrary to what the author claims. Then again, actualized differences, whatever they are, may behave differently. Who can tell?

We urgently need an academic investigation into whether actualised energy differences are afferent.
