How do you meaure how much a human brain can hold?

Question

They always talk about computers will be able to hold more than a human brain how do we actually know how much a brain can hold.

If every single person is different can't the amount of things a brain can hold differ also, If you have also 7 billion people how can you say a computer will hold more than a brain if you cant even figure out the average amount a brain can hold. You would have to test billions of people to get a true answer and that has never been done.

Answer 1

Assuming that brain synapses are on off switches, count

up the number of synapses and that is the number of

bits capacity a brain has. Now, in the modern world, there

is interest in these things called "microtubules"  that

are part of the axons in the brain. These little tubes are thought

by some people to be like quantum computers, each

possibly having a huge number of states, so you would

have to multiply that number times the number of microtubules, times the number of axons or synapses.

Answer 2

well the human brains more better than a v good comp

the human brain can do things worth 100 terabytes while a good comp can only do 100 gb

n if u wanna c how intelligent a person is by looking at his/her brain u shud see how many curves it has

the more curves the brain has the more intelligent the personis

Answer 3

The "computing" capacity of the brain is extrapolated from the study of the processing that occurs in an eye's retina.

The number of neuron in a brain is something that can be estimated, as well as the number of synapses. This allows an estimate of the memory capacity of the brain.

If you disagree with those rough order of magnitude estimates (and this what those are: estimates) feel free to propose a more suitable method.

Oh, and about testing: statistics shows that 30 samples is enough to establish average and standard deviation with acceptable certainty. From this a pretty good idea of the complete population can be established. No need to test thousands, 30 randomly selected individual is enough (although having 1000 is indeed much better)

Answer 4

The human brain has about 10^11 neurons and 10^14 synapses.  If you evaluate each synapse as one bit, that's 100 terabits.  That much disk capacity costs less than $2000.  In terms of raw storage capacity, computers can hold far beyond a single brain already.
