How much human brain memory capacity?
2 gb according to my mate Antony*Edit* Lol, try something like 2 Terabytes and you are still going to be very far from the truth. I don't think that it is possible (yet) to evaluate the capacity of the human brain. The fact is that a person can remember hundreds of movies, songs, books, events from the past, pictures, faces, names, phone numbers, etc., that if all those memories had to be put on a hard drive, terabytes upon terabytes wouldn't be enough.A quote from some researchers."The human brain contains about 50 billion to 200 billion neurons(nobody knows how many for sure), each of which interfaces with 1,000to 100,000 other neurons through 100 trillion (10 14) to 10quadrillion (10 16) synaptic junctions. Each synapse possesses avariable firing threshold which is reduced as the neuron is repeatedlyactivated. If we assume that the firing threshold at each synapse canassume 256 distinguishable levels, and if we suppose that there are20,000 shared synapses per neuron (10,000 per neuron), then the totalinformation storage capacity of the synapses in the cortex would be ofthe order of 500 to 1,000 terabytes. (Of course, if the brain'sstorage of information takes place at a molecular level, then I wouldbe afraid to hazard a guess regarding how many bytes can be stored inthe brain. One estimate has placed it at about 3.6 X 10 19 bytes.)"EnglishThe Free Encyclopedia3 140 000+ articles日本語フリー百科事典641 000+ 記事DeutschDie freie Enzyklopädie1 000 000+ ArtikelEspañolLa enciclopedia libre545 000+ artículosFrançais
