how does our brain store all the memory and recall it?

Answer 1

Each memory is stored inside a unique cell created just for that purpose. The pathway back to that cell is simply an energy impulse. We cannot recall a memory until that single cell becomes excited by the energy impulse. Over time, the pathway to most unused cells weakens and we forget the vast majority of our experiences. On the other hand, the more we recall a memory along its path, the more entrenched that path becomes across our brain.

When there is a name or some other packet of information attached to a memory and we can remember the memory but not the name, it is our brain's (sometimes temporary) inability to find the other cell and make the connection. When we have an epiphany or a sudden recollection of the pathway between the two, the cells can become so excited, the energy feedback can cause the release of endorphins which gives us that happy/relieved/satisfied little booster feeling.

BTW: our dreams at night are caused in part by our brain sorting and storing the day's intake of memories

Answer 2

Our brains work similar to computers. There are parts of the brain that store everything we experience into long term memory. We dont recall everything in long term memory in great detail, but it is all there. Our short term memory has less storage space, but we remember things in more detail. We remember things by categorizing things into concepts. So when that concept is brought up, it triggers numerous ideas that we have related to that concept. For instance, if I say the word sport, no doubt a number of different sports will come into your head. Which ones will depend on your experiences and the way you have stored these memories. Things that we have learnt in the past but no longer use get pushed back into long term memory. Say you learnt a second language in school. You may have forgotten most of what you learned, but if you started using that language again, you would start to remember things easily because you have triggered that part of your memory to become active again. This is why its always easier learning something a second time round.

Answer 3

That's a huge area of research, and it isn't well understood (although we're making progress). The answers so far range from OK to very, very bad. Don't rely on them.

One of the most interesting and informative case studies is that of "HM"

http://en.wikipedia.org/wiki/HM_(patient)

who lost the ability to make new memories after an experimental surgery to cure his epilepsy.

At a cellular level, some of the most important work has been done by Eric Kandel, who won the Nobel Prize for his work. It isn't the sort of work that's easily summarized in a short post, however.

Answer 4

Little mern that spend their whole lives remembering one thing,
So tiny they are they woiuld be of nanno size to nannobots, work that out with a slide rule and paper.

Answer 5

I think it has something to do with Psychology more than Biology. I dont really know how to spell this word, but i think it has something to do with your Psychque or w/e its called.
