I know it has been clarified,
But to be clear, memories are just connections between your vision, your emotion, your hearing, your taste, etc etc attached to your processing.
A memory is actually physically formed in the brain. People with dementia have a brain that is physically deteriorating, the brain shrinks in size, they lose the neurones.
Memory is physical! It would take 2 mi utes on google or a trip to the library to learn this. How on earth do you think atheists could exist if we had an etherial memory of no physical foundation, or if emotions were not fully explained by the physiology and their effects?
These are all well understood. It is true to say we don't k ow the exact mechanism of how a memory is laid down, but that is due to the difficulty in testing and examining a living brain in real time. It isn't because the physiology is missing,
Trauma and damage to the brain taught us much about how it works, it has been long appreciated that memory is physical, just as it is with a computer. You look at a cd and wonder how info is stored in a physical form....so with a dvd, it stores images, video, music, writing etc.Because we access the memory in what appears an abstract way, we don't see the neurons firing, not until the recent FMRI's could we see them work. Just as with computers etc, memory is stored physically, though in a very different way to computers.we don't have a specific memory region, we make memories by making connections.
Everyone however has had a taste of how memories are laid down, ever heard a song and a smell been sent back 15 years to a specific memory?
When we revise for exams, knowing how memories are made, stored and accessed, we revise in a manner that uses all of the senses. So I draw,
I use colours, I read the words out loud, I make imaginary connections with the words. I even sometimes play songs when revising multiple exams so that nearer the exam I play the same songs again and it works, there will be portions of a song and a very specific and vivid memory from the revision will come to mind, usually something i had to put extra effort into learning.
My point is, these are well understood and all 100% explainable via the physical.
With respect, you are bringing up things long understood. Perhaps have a quick look on a reputable science/medicine/biology site online before you mention it as then you can learn for yourself what we do actually know.
This took 10 seconds to find...
Ask a neurosxientist: How and where are memories stored.
