This has probably been asked before, but I could not find it.

We often liken our brains to computers.

How many GHZ is the human brain?

How much memory does it have and how much storage space could it hold?

The human brain is far superior to any computer we can create for a very very long time to come. As far as memory. I believe it has the capability to store every moment of your entire life from birth till death.

not true at all! after this question i searched and computetional power is not far, BUT to make a lifeless "thing" to think like a human?!... well that means we need to know how it (we) works! and that is not gonna be coming soon! as for the capacity it is not unlimited thats why your (our) brain erases information that we don't really use [thats how it can tell what to keep, the information we use the most "repeating" are the information that keep us alive (or at least they were for a few thousant years)] and dump the rest to make room for more (needed) information AND to make the access to the (most needed) information faster. every memory we have is still with us because we learned something very valuable from it!

Your brain does not erase information unless you become severely brain damaged. You may have trouble recalling information, but that doesn't mean you've forgotten it. It's a shame I didn't understand half of your comment. I suggest using better punctuation so that people can read your comments without being overwhelmed with confusion. There's otherwise no point in you posting.

even if i posted here every reshearch about the brain ppl would still think they are god... just like Seb! Our brain is like anything else in the cosmos just open your eyes and see it... it has limits and those limits can be exceeded by a computer, and if you think that this is bad thing... dude, you are wrong! because the day we will know HOW WE WORK (to do that we need that EXTRA super computational power) is when we will be able to improve our selves (mentaly and biologicaly) and finaly come to every scientists dream... man+machine synergy... then the entire cosmos will be ours! and i mean that in the best way possible! can you imagine if you could "connect" your brain with mine? an entire 10 day long conversation would occure in miliseconds! 1.000.000 scientists could solve problems like "how to create a 28th dimention"! our brain is a tool not very advanced compared to what lies in the near future! Hell 20 years ago there was no SMS and today we send like trillions of them EVERY day! just take a look at the link cause i'm sure you haven't and then do some research around the www you will see tha in the next 20 years things will be vastly changing!

I don't actually think it is like a computer as much. The brain works diffrentally. It stores, and process information all in one part.

Well thats what I think.

the brain is divided into many different sections..for example..there is a section dedicated for sight, hearing, long term memory...etc..so yeah..its MANY different parts work as one?

1 Brain. That is what I meant.

I don't know, but if I had to guess mine it would be 400MHz.

I don't think this question can be answered because the brain doesn't refresh and lose all it's information a million times a second. I like to think of the brain as a giant hard drive constantly being fed with information with input devices also known as ears, eyes and nerve.

11:00 Well i was watching a show the other day called "Did you know?" and i think they said something about this... give me a sec plz!

11:07 Ah! here it is http://www.youtube.com/watch?v=cL9Wu2kWwSY Jump to 4:04 for the brain part! (at 4:07 it gets REALLY SCARY in my opinion) hmmm lets google some more...

11:24 Now thats very intresting http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.136.7883&rep=rep1&type=pdf

11:30 i wonder... i am 25 years old... how many great great GREAT things will i see? and what will be my part in them??? the future is a mindbubbling mystery! mindbubbling i say at least!

The brain is far more powerful than anything humans can ever make, because the creation can never be as good as the creator. I'd like to see anyone record a video that far exceeds HD 24 hours of the day 7 days a week. It is not possible for something like that to be recording constantly for a couple hundred hears.

The brain is probably a couple million teraflops in each "core", and probable a couple of billion cores.

to the contrary, I believe the creator can ALWAYS create a creation to a higher degree then what the original creator was.

It's a single-core at 1Hz. It can, at best, do 1 FLOPS, though mostly it performs at a much lower speed than that. What makes it unique, however, is it's terabytes of RAM and the ability to think for itself. All in all, AMD FTW INTEL AND THE HUMAN BRAIN SUCK OLOLO TROLL!

The brain does not have one central processing core, it is a network of billions of neural connections all acting together as "the brain". So it doesn't work at a speed, it is not an electrical component, you cannot compare the 2 at all! What makes humans so incredible, is not the brain, as such, it is the mind held within!

well all the neural connection use a combination of electrical and chemical reaction to "process" data so it is an electrical component (partly) besides the speed (time) in witch we think is measurable and thus existing. let me quote Hans Moravec "Computers have far to go to match human strengths, and our estimates will depend on analogy and extrapolation. Fortunately, these are grounded in the first bit of the journey, now behind us. Thirty years of computer vision reveals that 1 MIPS can extract simple features from real−time imagery−−tracking a white line or a white spot on a mottled background. 10 MIPS can follow complex gray−scale patches−−as smart bombs, cruise missiles and early self−driving vans attest. 100 MIPS can follow moderately unpredictable features like roads−−as recent long NAVLAB trips demonstrate. 1,000 MIPS will be adequate for coarse−grained three−dimensional spatial awareness−−illustrated by several mid−resolution stereoscopic vision programs, including my own. 10,000 MIPS can find three−dimensional objects in clutter−−suggested by several "bin−picking" and high−resolution stereo−vision demonstrations, which accomplish the task in an hour or so at 10 MIPS. The data fades there−−research careers are too short, and computer memories too small, for significantly more elaborate experiments."
