    How much data can the human brain hold?
    >> Anonymous 02/23/10(Tue)00:11 No.364156
    So you decided to actual ask the question.

    If I remember my psychology book, the long term memory can hold an unlimited amount of information.

    Thats like asking how much weight a human can lift...

    Depends on how much theoretical space one memory or idea might take up over another

    You have 100 billion neurons, each can form 10000 connections with other neurons.
    Lets assume, for the sake of simplicity that each of those circuits can only be on or off. Also lets say that only 50 billion neurons are used for memory retention and only form 5000 connections each.
    I have no real clue how to compute this, only that the number of possible circuits, and thus storage capacity is very, very large.
    Lets take one Neuron (N0) and its relation to 5000 other Neurons with which it has formed connections (N1-N5000) Thats already 5kbit, now take the next Neuron (N1) and its connections to the others (N2-N5000), another 4999bits, and so on...
    Also thats without multiplexing of informations. (i.e. when circuit no. 406756 and 56386 are active at the same time, a different information is encoded as when circuit no. 406756 and 2486745 are active)


    If someone with more knowledge in combinatoric could correct/help me here I would be very glad, not sure if above estimate is correct.

    organic memory is super fusked. it's the number one reason to transfer to machine-consciousness.

    in reality it cannot hold much, but in practice it can hold a fusking hueg amount. there is some spooky procedural continuous compression going on. we are basically nothing but memory, in brain:computer analogy it would be that we are nothing but ram. not even a cpu as such, the non-human-specific parts of our brain are all about maintaining the body.

    we, consciousness/sapience/sentience, are entirely like ram on a computer, with constructs stored in it that act on other pieces of memory and new constructs being made and new memory being added all the time and etc. it's weird!

    this is a difficult question to answer, because conciousness, memory and all that jazz to do with their physical basis is currently so very poorly understood

    oh yeah, forgot something.
    Above start of estimate is assuming that only 2 neurons are connected with each other, the 5000 could of course form 2500 single circuits or 1 big one or any combinations in between.


    Like i said, im not very good with combinatorics.

    I think it's possibly infinite. There are some people who have photographic memory of everything.

    We calculated this a few weeks ago. My number was something like ten billion gigabytes. Most of that is inaccessible to you and goes to the upkeep of everything that isn't able to be controlled by you.

    there are no memory units there is a great big block of assumed rules, the reason they are assumed and triggers for their consideration. the triggers happen automatically (unless we force a new rule to intercept), and we can look up the reasons a rule is assumed on command (remembering something).

    that's long-term memory, at least. short term memory is more like a narrative with things we have picked out as important (based on rules) given precedence. but it is all there more-or-less, for some kind of period (natural waking day? weeks, months? lolidunno). short term memory is turned into long-term memory over time (new rules are formed). the process for this is another big lolidunno. it's doesn't appear to be conscious, and in fact if there is a subconscious this task would seemingly be its purpose and domain. it is an automatic process divorced from consciousness, using all (?) the rules we already have to incorporate anomalous short-term memories into the overall ruleset.

    instincts/reflexes are triggers attached directly to behavior that cannot be intercepted. these are just a facts of life, they are different from conditioned responses that CAN be intercepted (given time and effort), no matter how extreme the extreme the conditioning. there aren't many of these, really, and they're very simple biological stuff, as well as just weird things (like hit on the knee-muscle makes you kick). the difference between these and short-circuits not attached to the consciousness are lolidunno.

    But even they too can filter out stimuli by deleting those memories. Only a very small fraction of what actually goes in to your brain is actually stored as memories. Also, not every neuron is engaged in active memory storage.

    Unfortunately, it appears that memories are not stored in cell blocks like computer data but rather are the connections from one cluster to another. It's really impossible to tell at this point.

    Also, I know nothing about neurology. Also also, there have been studies done apparently where instantaneous memory is roughly 7 things because people can quickly memorize phone number.

    That is why science is shit. If you don't know something, instead of saying you don't know it, you go into an elaborate essay about absolutely nothing and waste fucking time.
