David Coppedge: Brain neurons “comparable to a library”


In the visual cortex:

Researchers at Max Planck, Rockefeller, and Duke Universities examined the connections in brain tissue from the visual cortex, the first stop for information coming in from the retina. It was a tall order. A news item from Max Planck, “No cable spaghetti in the brain,” describes the cabling nightmare:

Nerve cells in the human brain are densely interconnected and form a seemingly impenetrable meshwork. A cubic millimeter of brain tissue contains several kilometers of wires. A fraction of this wiring might be governed by random mechanisms, because random networks could at least theoretically process information very well. Let us consider the visual system: In the retina, several million nerve cells provide information for more than 100 Million cells in the visual cortex. The visual cortex is one of the first regions of the brain to process visual information. In this brain area, various features as spatial orientation, color and size of visual stimuli are processed and represented.

Not Spaghetti Cables

But they did not find randomness. They found a well-organized structure like a library.

Here’s the Max Planck news item (November 23, 2015).

The more we study, the more complex it gets. Consider:

Our neurons’ electrical synapses are the dark matter of the brain. These aren’t the familiar chemical synapses but a second set, the electrical synapses that enable currents to travel directly between neurons from pore to pore. A recent study in fruit flies shows that without the little-understood electrical synapses, neurons’ reaction is much weaker and some of them became unstable.

Memory leans more on the brain’s electric field than on neurons. MIT researchers compare the electric field to an orchestra conducting the neurons as players. The neurons associated with our memories may change; it’s the electric field that holds the memories together, the neuroscientists say.


The brain unfolds like a drama, with neurons in different roles. Researchers studying fruit flies hope that spotting the stages at which human neurons go missing or wrong can help develop treatments to insert or replace them. Human and fruit fly brains are strikingly similar but with vastly different results. Clearly, the brain is not all we need to know about a life form.

So memory - and thus intelligence - relies on incredibly complex arrangements and activity of neurons, electrical fields, etc. Complex physical form and function, then, appears to be necessary (even if not sufficient) for the operation of intelligent minds. If so, how could something intelligent be responsible for the initial creation of complex systems (biological or otherwise)? I don't know the answer to that, and I believe nobody does. dogdoc
An army might be a better analogy. Books don't know where they belong on the shelves. Neurons do. After basic training, they're sent out on glial railroads to the front line of the cortex. Each neuron knows which camp to move to, and which row and column in the tents. Each neuron knows its commander and its squadmates, and makes the appropriate connections after dropping its knapsack. polistra
"The more we study, the more complex it gets. " Yes, it certainly does, but in the end, it doesn't matter one iota how complex, how interdependent, how efficient, how well designed things are. The god of Chance, working through evolutionary processes is believed to be omnipotent - literally capable of creating anything. So nothing is going to change their mind. The data, the evidence, the facts simply don't matter. Whatever exists is believed to be within the creative ability of evolution. Their minds are already made up. Evolution did it. Period! Not even discoveries of codes, layers of complexity, inter-dependency, etc. can phase them. They just ramp up their faith to accommodate whatever it is they need to believe in. Jesus said "with God all things are possible." In contrast, evolutionists say "with evolution, all things are possible." There is faith on both sides of the fence! We get accused of using an argument from credulity. I admit it. Yes, you're exactly right! The faith of evolutionists in the unlimited creative powers of evolution is incredulous to me. You accuse us of using an argument from credulity? OK, fine. We accuse you of using an argument of faith - believing incredulous things that you can't demonstrate to be true. So we're even. It's a free world. Believe whatever you want to. No matter how strong your faith in evolution may be, it doesn't make it true. It doesn't mean that the creative powers of evolution are capable of creating what we see. tjguy
