The first technique I drew upon was priming. The priming of a memory occurs because of the peculiar "connectionist" neural dynamics of our cortex, where memories are distributed across many regions and neurons. If we can recall any fragment of a pattern, our brains tend to automatically fill in the rest. For example, hearing an old Madonna song may launch a cascade of linked memories: your high school prom where it was the theme song, your poorly tailored prom outfit, your forgotten prom date, the stinging embarrassment when you threw up in the limo.
