The Mind Boggling Speed of the Human Brain

 

In 1992 Gerald D. Fischbach wrote1:

‘the most complex structure in the known universe, complex enough to coordinate the fingers of a concert pianist or to create a three-dimensional landscape from light that falls on a two directional retina’ … ‘the current version [of the brain] is the result of millions of years of evolution. It is difficult to understand the brain because, unlike a computer, it was not built with specific purposes or principles of design in mind. Natural selection, the engine of evolution, is responsible.’ [Emphasis added]

20 years later, on August 2, 2013, Tereza Pultarova wrote an article in Engineering and Technology Magazine2:

Japanese K Supercomputer - credit RIKENLargest neural network simulates 1 per cent of brain

A network consisting of 1.73 billion nerve cells connected by 10.4 trillion synapses has been created using the power of a Japanese supercomputer.

Despite being the biggest neuronal simulation to date, the process requiring 82,944 processors only represented about 1 per cent of the neuronal network of a human brain.

The supercomputer completed in 40 minutes the equivalent amount of activity that is observed to take place in the living brain within one second.

The teams from the Okinawa Institute of Technology Graduate University (OIST), Japan, and the Research Centre in Julich, Germany, ran the advanced simulation software NEST on the Japanese K supercomputer, capable of processing 8 petaflops3 of information per second.

Overall, the experiment needed memory equivalent to that of 250,000 PCs.” [Emphasis added]

 

I wonder if today, based on information we know now, Mr. Fischbach can seriously say that the human brain was not built with design in mind … even our very complex brains cannot engineer a computerized brain that even comes close to the mindboggling speed of our brains. The evidence points to a brain that was engineered by a designer, not to a brain that could have happened by random chances and accidents (‘Natural selection’), even given ‘millions of years’ of so-called-time.
