Where does memory actually go when you forget?

Question

Where does memory actually go when you forget?

In: Biology

Answer 1

It is lost to the inevitable entropy of the universe. Memory just like any information is a certain arrangement of informational bits. When your brain repurposes unused neurons, the old information they encoded is being jumbled up and the information bit arrangements are now for all intents and purposes randomized. This randomization IS the loss of information (and loss of information is entropy).
