What 'Architecture' is the brain?
-
Whatever may be the architecture, but while making the design of my brain, The Almighty decided to dedicate a fairly large amount of processing power to a separate unit, that enables me to do excellent manual transmission. :)

Yes, but only while kept close (1 meter or less) to specimens of opposite sex. Turns out to be unpredictable. :) But never had an issue with doing manual transmission. Even in the presence of the said specimen, which actually enhances the capabilities. ;)

As processor data and addressing widths have increased overtime from Intel's 4004 4bit processor to the now very common 64bit AMDs and Intels and then on to multicore, this got me on to thinking as to what 'architecture' the human brain might be; if it is at all comparable to a slice of silicon. My own thoughts on the matter are it must be at least a 16 bit/16+ core processor backed up with several 100 GBytes of memory, but with a poor memory management system! My reason for only 16bits is have you ever tried multiplying or dividing two 4 digit numbers in your head? Or tried to remember an eleven digit phone number someone has just told you; hence the poor memory management system? The 16+ cores; well when you think what the brain does consciously and unconsciously and all the parallel processing that takes place, one or two cores just wouldn't be enough.
At least the higher level functions ("the human") are implemented in a huge, freely reprogrammable FPGA, also known as the cortex. The hardware elements are not uniform, there are special elements like spindle neurons which nontheless work more or less by the same principle. Unlike todays FPGA's, the nodes support fuzzy logic, can be reinforced / dampened on the fly / by read access. The lower level functions ("the animal") are distributed over the huge lump blow the cortex, work (in my understanding of what we know today) similar, but with different specializations and importance of initial state.
Personally, I love the idea that Raymond spends his nights posting bad regexs to mailing lists under the pseudonym of Jane Smith. He'd be like a super hero, only more nerdy and less useful. [Trevel]

Your brain can remember thousands of shapes, figures and faces. How much memory does a computer need for that?
Well I did say several hundred GBytes, maybe I should revise that to several hundred terabytes or even petabytes! Which also leads to another interesting question, can you exhaust the storage capacity of the brain or would it work like a FIFO system - First In, First Out?
According to this[^] it is between 1 and 1000 Terabytes (nothing like hedging your bets :) ) but is probably 3. Although I disagree, I calculate it as 3.85 TB. (I have been getting my neurons to number off whilst I was typing this.)

Party trick of mine in high school after using an associative memory recall technique. Haven't tried it in years and don't actively use the memory recall techniques any more. Close friends reckon I have "the memory of an elephant", I reckon I'm just genetically predisposed. Or something.

LOL. Hmmm, that makes for very interesing reading; thanks for the link. I especially find this bit very useful: "Each synapse possesses a variable firing threshold which is reduced as the neuron is repeatedly activated." This explains to some degree how the act of learning something is achieved. The more something is repeated, the better the connections involved become and hence, it becomes second nature.

That's how I do it to remember the phone number but I also associate the phone number to either a word or number (depending on my mood) so that I can associate them with a person/place. Not unlike PK/FK relationships in RDBMS's.

Definitely RISC -- all those floating point operations have to be programmed later.

Seems to me to be the only way in which the animal brain is remotely similar to our crude silicon imitations. A sort of Electro-Lithography instead of Photo-Lithography.

Massively parallel!!! Yeah for sure!! For the amount of memory, my recollection would be the amount of synapses would be a couple of thousand of petabytes, assuming one byte per synapse, which is certainly too low, and by simply ignoring the bytes needed to describe the neurons themselves (which is then definitely gross). But as someone points out, this is only the visible part of the iceberg, given most of what we do is unconscious, there is a massive amount of processing power in the lower cortex. But how about about considering the immune system as a data processing unit? Given there are all kinds of distributed computing all over the body, we are still very far away from putting together that sort of computing power.
You can't turn lead into gold, unless you've built yourself a nuclear plant.

The human brain is divided into several regions, each composed of neural networks. The higher conscious brain is mostly the outer folded layer of the brain, a layer only found in mammals, and (obviously) greatly expanded in humans, thus allowing our relatively very high intelligence. Other parts of the brain regulate body functions, for example, controlling muscle movement. This is why you don't have to think which muscle to move and exactly how to move it - your higher conscious brain just says "do this" to that lower part of the brain, which translates "do this" into "contract this muscle by this amount" and "relax this muscle by this amount" etc. Some other parts control body temperature, moods, some reflexes, breathing, digestion, heart rate, and all that other stuff. And yet other parts process sensory information - like vision - and by the time it gets to the conscious part of the brain, its all "there's a car" and "that's a house" instead of wavelength amplitudes and stuff. And there are parts dedicated to indexing long-term memories, like the hippocampus, and yet other parts dedicated to language grammar, syntax, vocabulary, etc processing (which explains why mentally disabled people can still talk in many cases - language is a "basic" function not requiring much intelligence). This is all built out of carbon-based chemicals. So the brain is a carbon-based architecture. It's so distributed it has no CPU. The "CPU" of the brain emerges from the billions of connections between individual neurons, which can be considered like a single node on a network whose topology is constantly changing. The firing of neurons in the brain is "controlled chaos". When your neurons aren't firing at all, your brain is dead. When the neurons are firing synchronously, in a repeating pattern, you're having an epileptic seizure. But when it's a combination of pattern and chaos, you're conscious and thinking. Pretty cool, huh?

I gave up when I couldn't spell "egg". Justine AllenI used to remember phone numbers by following techniques: 1) Splitting it into group of numbers 2) Taking an image snapshot and remembering the image (Ex: shop displays etc) 3) Using some algorithm Used to remember a lot of phone numbers about 10 years back, but now its very few. Looks like memory area is getting crowded with other feature/functionalities :)

Have a read of "Enchanted Looms: Conscious Networks in Brains and Computers" by Rodney Cotterill[^] He asks the question will computers ever develop consciousness? Simple answer: yes. But along the way he also makes it very plain how computers and brains are fundamentally different. Unfortunately, he has now passed away so there's not much chance of him updating this work to put the latest references and research into it.

Interesting take--except for the small details of stuff like 1)emotion/irrationality and 2)ability to create new ideas.

Few million cores - more like a cloud of small computers. No bits - it's chemical and it is not binary. It has slow information transfer: it's only partly electrical, and in part it is chemical. It has true randomness though - without "pseudo" :) - including self-organising logic (damage a part - other will learn to do its job) In brief, nothing close to any computer.

Searching just now on Hameroff, using the query (( hameroff google marriage )) finds Hameroff's 2007-sept-21 "Google Tech Talk" "A New Marriage of Brain and Computer". He repeatedly uses "The Bing Experience" as a term, evidently "Bing" has long been a buzzword among neuro-philosophers, something I didn't know till just now. This talk is "different material", way different from the stuff which has been on his "Quantum Consciousness" page ( the Penrose-Hameroff microtubules ) for years - quite an entertaining talk really, nice slides.
