how many Giga bites does the human brian hold if converted?

Question

may be this is a stupid question........

Answer 1

The brain is a neural net, so it doesn't hold 'data' in the traditional sense. I have no idea, so here's a link about neural nets. http://richardbowles.tripod.com/neural/neural.htm

Answer 2

And here is a stupid attempt to answer!
There are approx 10^13 neurons in the human brain. They connect together by synapses, where the axons dendrites etc interface and neurotransmitters( ionised molecules) mediate inhibitory or excitory signals between them. Most of these processes are required to mediate sensing/control/homeostatic functions within the rest of the body. Even if we associate just a single bit of information with each synapse, and allow that the 'memory' occupies just one percent of these, the minimum human memory capacity would be of the order of 2^(10^13) bits!
This comes out as 10^16 terrabits!. However,, given that the brain is massively redundant and many functions can be duplicated by other networks within the brain, the actual memory capacity is probably several orders of magnitude lower than this. Bear in mind that, although new brain cells are not produced much beyond birth, new neural connections are constantly made in response to various stimuli including trauma. In that respect the brain is constantly reconfiguring its 'hardware'. In fact 'learning' as we know it may not just depend on stored information but instead of a reconfiguration of the synaptic 'web'- rather like 'neural nets' can be 'trained' in AI technology.

Answer 3

The whole idea to think about brain capacity in terms of Bytes is absurd. We do that because that's the only way that we can quantify memory. There are many things that we humans have still not fully understood and the brain is just one of those things. There's other super intelligence at work putting the whole human structure together.

Answer 4

The human brain is unlimited - it has no physical limit.

Or if it does a lifetime is not enough to fill it.

Theres lots of research to show that we remember everything that has happened in our lives - its just bringing it up into our short term memory that is the problem.

Short term memory is limited though, resarch shows we can remeber about 7 things in our short term, and for around 15 seconds. If it is not put into our long term memory, than its lost.

Also we have a sensory memory, our eyes and ears remeber things for a very short amount of time - an example is when someone talks to you and you werent listening to them, you can recall what they said around a couple of seconds after - after that than its gone.

Answer 5

Agreed. it's a bad comparison.

In thorey, can hold an almost infinite number of different states, since it can use cyclic activity.

So far as what we can remember, probably only a few billion gigabytes equivalent, but the human brain is like a computer that changes completely every time it's used.

Answer 6

Instead of GBs of Hard drive space in a brain, I'd go with RAM, how much we can remember before forgetting something, and how many things we can remember at the same time, also how much does this RAM inside alow us to do i.e. multitasking... people that can multitask very well would have a lot of RAM, also people that can remember things, obviously the things we are thaught would be stored in our "hard drive" for later use when they are pulled out it and temporalily store in our RAM before being replaced with something else.

Answer 7

I have no idea. Consider that you can easily identify dozens or maybe even hundreds of people. Also consider how quickly you can identify them. Even modern computers could not match your speed. So I'd say the number is quite large.

Answer 8

Depends on the brain....

One thing is for sure though, the further to the right or the left you are, the smaller the capacity.

Answer 9

It contains 10,000 Metabytes, I think?
