And is not even trying to be, according to Robert Epstein at Aeon:

To understand even the basics of how the brain maintains the human intellect, we might need to know not just the current state of all 86 billion neurons and their 100 trillion interconnections, not just the varying strengths with which they are connected, and not just the states of more than 1,000 proteins that exist at each connection point, but how the moment-to-moment activity of the brain contributes to the integrity of the system. Add to this the uniqueness of each brain, brought about in part because of the uniqueness of each person’s life history, and Kandel’s prediction starts to sound overly optimistic. (In a recent op-ed in The New York Times, the neuroscientist Kenneth Miller suggested it will take ‘centuries’ just to figure out basic neuronal connectivity.)

eanwhile, vast sums of money are being raised for brain research, based in some cases on faulty ideas and promises that cannot be kept. The most blatant instance of neuroscience gone awry, documented recently in a report in Scientific American, concerns the $1.3 billion Human Brain Project launched by the European Union in 2013. Convinced by the charismatic Henry Markram that he could create a simulation of the entire human brain on a supercomputer by the year 2023, and that such a model would revolutionise the treatment of Alzheimer’s disease and other disorders, EU officials funded his project with virtually no restrictions. Less than two years into it, the project turned into a ‘brain wreck’, and Markram was asked to step down.More.

If the brain is not a computer, it follows, that a computer is not a brain. Which means that the big claims of AI fans are going to remain what they have always been, mostly hype.jstanley01

The brain is like a computer this creationist says. or rather the brain is just the mind which is just a memory machine. nothing to do with the soul. the flaw in this Epstein idea is that all creatures brains have as much or close all these neurons and lights and flashes. SO WHAT? Creatures are super stupid. its not a interest in the human brain but in why its better then others. And how to fix it. Heal it. Its once again them looking at the parts without seeing the whole. The ghost in the machine is one thing. the machine should not be that complicated to understand if mice have the same machine.Robert Byers

is this related note:
"Complexity Brake" Defies Evolution - August 8, 2012 Excerpt: Consider a neuronal synapse -- the presynaptic terminal has an estimated 1000 distinct proteins. Fully analyzing their possible interactions would take about 2000 years. Or consider the task of fully characterizing the visual cortex of the mouse -- about 2 million neurons. Under the extreme assumption that the neurons in these systems can all interact with each other, analyzing the various combinations will take about 10 million years..., even though it is assumed that the underlying technology speeds up by an order of magnitude each year. http://www.evolutionnews.org/2012/08/complexity_brak062961.html
Which is really not that surprising since they have not even realistically modeled the simplest cell on earth yet:
To Model the Simplest Microbe in the World, You Need 128 Computers - July 2012 Excerpt: Mycoplasma genitalium has one of the smallest genomes of any free-living organism in the world, clocking in at a mere 525 genes. That's a fraction of the size of even another bacterium like E. coli, which has 4,288 genes.,,, The bioengineers, led by Stanford's Markus Covert, succeeded in modeling the bacterium, and published their work last week in the journal Cell. What's fascinating is how much horsepower they needed to partially simulate this simple organism. It took a cluster of 128 computers running for 9 to 10 hours to actually generate the data on the 25 categories of molecules that are involved in the cell's lifecycle processes.,,, ,,the depth and breadth of cellular complexity has turned out to be nearly unbelievable, and difficult to manage, even given Moore's Law. The M. genitalium model required 28 subsystems to be individually modeled and integrated, and many critics of the work have been complaining on Twitter that's only a fraction of what will eventually be required to consider the simulation realistic.,,, http://www.theatlantic.com/technology/archive/2012/07/to-model-the-simplest-microbe-in-the-world-you-need-128-computers/260198/
And although I agree with the author that memories are not stored 'in' the brain, the reason I agree with the author is quite different from the materialistic view of mind that he has.
Brains on Fire: Dr. Steven Novella Explains, "The Mind Is the Fire of the Brain" - Michael Egnor - December 18, 2014 Excerpt: The difference between a memory and a representation of a memory is obvious. Right now I remember that I have an appointment at noon. I'm writing down "appointment at noon" on my calendar. My memory is my thought that I have an appointment at noon. The representation of my memory is the written note on my calendar. A thought differs from a note. A thought is something I experience; a note is something I write. My memory is a psychological thing. My note is a physical thing. My memory is represented in my note. My memory is not the same thing as my note. A memory is not the same thing as a representation of a memory. I hope that's clear. I'm not sure how I can be clearer. - Michael Egnor is a professor and vice chairman of the department of neurosurgery at the State University of New York at Stony Brook. http://www.evolutionnews.org/2014/12/brains_on_fire092151.html A Reply to Shermer Medical Evidence for NDEs (Near Death Experiences) – Pim van Lommel Excerpt: For decades, extensive research has been done to localize memories (information) inside the brain, so far without success.,,,,So we need a functioning brain to receive our consciousness into our waking consciousness. And as soon as the function of brain has been lost, like in clinical death or in brain death, with iso-electricity on the EEG, memories and consciousness do still exist, but the reception ability is lost. People can experience their consciousness outside their body, with the possibility of perception out and above their body, with identity, and with heightened awareness, attention, well-structured thought processes, memories and emotions. And they also can experience their consciousness in a dimension where past, present and future exist at the same moment, without time and space, and can be experienced as soon as attention has been directed to it (life review and preview), and even sometimes they come in contact with the “fields of consciousness” of deceased relatives. And later they can experience their conscious return into their body. http://www.nderf.org/vonlommel_skeptic_response.htm
At the 17:45 minute mark of the following Near Death Experience documentary, the Life Review portion of the Near Death Experience is highlighted, with several testimonies relating how every word, deed, and action, of a person's life (all the 'information' of a person's life) is gone over in the presence of God:
Near Death Experience Documentary - commonalities of the experience - video https://www.youtube.com/watch?v=e2958DDp4WM Matthew 12:36-37 “But I tell you that every careless word that people speak, they shall give an accounting for it in the day of judgment. For by your words you will be justified, and by your words you will be condemned.”

'Afterlife' feels 'even more real than real,' researcher says - Wed April 10, 2013 Excerpt: "If you use this questionnaire ... if the memory is real, it's richer, and if the memory is recent, it's richer," he said. The coma scientists weren't expecting what the tests revealed. "To our surprise, NDEs were much richer than any imagined event or any real event of these coma survivors," Laureys reported. The memories of these experiences beat all other memories, hands down, for their vivid sense of reality. "The difference was so vast," he said with a sense of astonishment. Even if the patient had the experience a long time ago, its memory was as rich "as though it was yesterday," Laureys said. http://www.cnn.com/2013/04/09/health/belgium-near-death-experiences/ Scientific evidence that we do indeed have an eternal soul (Elaboration on Talbott's question “What power holds off that moment — precisely for a lifetime, and not a moment longer?”)– video 2016 https://www.facebook.com/philip.cunningham.73/videos/vb.100000088262100/1116313858381546/?type=2&theater Molecular Biology - 19th Century Materialism meets 21st Century Quantum Mechanics - video https://www.facebook.com/philip.cunningham.73/videos/vb.100000088262100/1141908409155424/?type=2&theater

If someone tells you that choosing to believe the Theory of Evolution over Intelligent Design is a no brainer, they're probably right.awstar
