Where do our memories get stored and how are they retrieved again? In one of Karl Lashley's 1950 papers, it is pointed out that information is not stored locally in certain area of the brain. Instead, it's stored distributively over the structure of the brain. I'm curious about how, in detail, is it stored in "structure." 

So what's the process when neurons try to encode information "distributively"? How do the brain retrieve these distributed information?
Long-term potentiation (LTP) is thought to be a major mechanism of long-term learning, in which neurons throughout the brain undergo permanent physiological changes (e.g., migration of AMPA receptors to neuronal terminal buttons) that allow maintenance of the memory trace. A simpler version of this would be the famous aphorism (and oversimplication) regarding Hebbian learning -- "cells that fire together wire together."
