how can our brain remember ? can't we replace hardisks in computer with a persons brain??...?

Answer 1

The problem with replacing hard disks with human brains is not with the biological construct of the brain, but rather with encoding and retrieval. Currently there are several models of human memory, and support for many of these models are compelling. Take the modal model of human memory. This model seperates cognitive function into several specific task oriented "compartments." A sensory memory, a short term storage area, divided into a visual spatial sketchpad, auditory loop, executive control, etc..., and a long term storage area. Another common model is known as the theory of spreading activation. Think of a pebble being thrown into a pond. Imagine the ripples spreading out from the site of impact. In the theory of spreading activation the pebble is the stimulus (memory to be encoded for storage) and the ripples size are a function of the impact the stimulus makes. The larger the impact, the more perminant the storage and the more easily the memory is retrieved. Now, even though both these models have support, and reasons for not supporting them, the fact is we're just not sure how memory is encoded, stored, and retrieved. Do individual neurons encode and store memory? Does the activation of specific neural pathways allow us to remember information we've stored? Currently we can't know, and until we do it would be impossible to utilize the brain in a manner that it was not endogenously designed for. Most importantly, however, is the question, "Why would you want to store information in a human brain instead of hard drive?" I can see the logic of wanting to add information from a hard drive to a human brain (Johnny Mneunomic style), but not the other way around. The brain, unlike a hard drive, is not a perfect storage unit for memories. Memories are maleable and imperfect. If you put information into a hard drive and wait a thousand years to retrieve it, you still get out exactally what you put in. If you put information into the human brain and wait a year, it is quite possible that you're not going to get retrieve exactally what you encoded and stored.

Answer 2

A couple of months ago a doctor wired chips into human brains in US, It was to give control over prosthetic arms. It worked but not very impressive. The doctor pointed out that it was just a start. Report was on a BBC feed, another doctor said that such an invasive procedure on a human should have been more ambitious in scope, because he was already doing at least that much with monkeys.

Answer 3

Yes, it can be possible if brain can be compatible with it and remain as such in the condition provided for a hard disk.

Answer 4

That sounds gayer than me on an ice skating rink wearing shortass shortyfuck shorts.

Answer 5

From where you will get brains to use as hard disc?(fun)
It will never be possible.

Answer 6

Do you have brain?

Answer 7

no itz impossible i suppose.....many things can b jus said...but cannot b done..
