How do our brains store and retreive memories?

Question

I want to know how our brains store memories... what are memories? Are they a chemical? Are they a physical thing? Where do they go? how does our brain find what it is looking for, and so fast?

Also, is it possible for memories or pictures in your head to be transmitted from your brain to a screen for others to see?

Answer 1

Memory is stored in the part of the brain called Hypoccampus. The process of storing memory is achieved by the transmission of electrical impulses along a neural pathway in the brain. It starts from the efferent nerves in the peripheral system (sense of touch, sight, smell, etc.) to the central nervous system (the brain). So each perception corresponds to a specific pattern of electrical impulses that travels up to the brain. And each pattern of impulses occupies a specific group or network of neurons... this network of neurons is the memory in the hypoccampus of your brain. So for example, you see a good looking person, that visual stimulus travels from the photoreceptors of the eyes to the cranial nerves to different parts of the brain until it reaches your memory center (hypoccampus). But this initial input of electrical impulses is weak because it has only travelled through your brain once, the first time, so it falls under the so-called "short-term memory". In order for you to remember it longer, you have to keep on thinking about it over and over because by doing so, you are strengthening the bonds between that paricular group of neurons through which the impulses travelled. That's why, for students, when they try to memorize their lessons, they read it over and over again, because it's true that repetition is the key to a good memory. The SAME INPUT (electrical impulses) travels up to the brain through the SAME PATHWAY (group of neurons) so this group of neurons becomes more enhanced than the other inside your hypoccampus and so you have a better chance of recalling this information than the other ones you instored in your brain.

I hope I was able to explain it clearly.

Answer 2

The two main theories are nerve connections and DNA. I think they both play a part.

Answer 3

Nobody knows that for sure, bt everyone wants to know.

And thats not possible yet :|

Answer 4

I don't know. That is best question I've ever seen on this site.

Answer 5

I have no idea I cannot even figure out how my mind work mind...mind?? do I have one of those tings??? LOL
