“The most complex object yet discovered anywhere in the universe is the organ that fills the space between our ears……How this unfathomably complex organization allows us to perceive, behave, think, feel, and control our environment presents us with what may be the most striking puzzle of fit we have yet encountered. The puzzle actually has three aspects. First, we must consider how over millions of years the primitive nervous system of our early ancestors evolved into an organ that has made it possible for the human species to become the most adaptable and powerful organism on the planet–living, thriving, and modifying the environment (both intentionally and unintentionally) from the tropics to the polar regions, and perhaps soon in outer space and on other planets.

Second, we must understand how it is possible for the intricate structure of the brain to develop from a single fertilized egg cell. Finally, we must try to comprehend how the mature brain is able to continue to modify its own structure so that it can acquire new skills and information to continue surviving and reproducing” [sic], ……Without Miracles by Gary Cziko

HUMAN BRAIN HAS MORE SWITCHES THAN ALL THE COMPUTERS AND ROUTERS ON EARTH

The human brain is truly awesome. (Wonderful?)

A typical, healthy one houses some 200 billion nerve cells, which are connected to one another via hundreds of trillions of synapses. Each synapse functions like a microprocessor, and tens of thousands of them can connect a single neuron to other nerve cells. In the cerebral cortex alone, there are roughly 125 trillion synapses, which is about how many stars fill 1,500 Milky Way galaxies.

These synapses are, of course, so tiny (less than a thousandth of a millimeter in diameter) that humans haven’t been able to see with great clarity what exactly they do and how, beyond knowing that their numbers vary over time. That is until now.

Researchers at the Stanford University School of Medicine have spent the past few years engineering a new imaging model, which they call array tomography, in conjunction with novel computational software, to stitch together image slices into a three-dimensional image that can be rotated, penetrated and navigated. Their work appears in the journal Neuron this week.

To test their model, the team took tissue samples from a mouse whose brain had been bioengineered to make larger neurons in the cerebral cortex express a fluorescent protein (found in jellyfish), making them glow yellow-green. Because of this glow, the researchers were able to see synapses against the background of neurons.

They found that the brain’s complexity is beyond anything they’d imagined, almost to the point of being beyond belief, says Stephen Smith, a professor of molecular and cellular physiology and senior author of the paper describing the study:

One synapse, by itself, is more like a microprocessor–with both memory-storage and information-processing elements–than a mere on/off switch. In fact, one synapse may contain on the order of 1,000 molecular-scale switches. A single human brain has more switches than all the computers and routers and Internet connections on Earth.

How Does the Speed of Thought Compare for Brains and Digital Computers?

For you created my inmost being; you knit me together in my mother’s womb. I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well…Psalm 139

“In a prior article about the human brain; “A Single Brain More Poweful Than All Computers Ever Made”, a comparison was made between memory capacity of modern computers and that of the human brain. This article compares the “speed of thought” between the two and –the human brain wins.

These authors mention design a number of times, apparently quite unselfconsciously. We would have to agree that design rather than random, undirected mutation explains why the brain is so fearfully and wonderfully made”….s8int.com

“In the early part of the 20th century, the Harvard University Observatory employed a small army of women — they were known at the time as girl computers — to identify images of stars on photographic plates and then to record the intensity and location of each identified star.

The job done by these girl computers has long since been taken over by the digital sort. We all know that digital computers are much better than we are at doing arithmetic, but over the past few decades computers have been taking over jobs, like playing chess or recognizing speech or carrying out symbolic mathematical manipulations, that we used to think of as the province of the human brain.

How close are computers, like HAL in the movie 2001, to matching those things that now only our brains can do? Our goal here is to compare the capabilities and speeds of the brain with those of modern-day computers.”
