Psychologists hypothesize that we lock in that memory by linking it to a where, that integrating many stimuli together helps us remember something particularly important. They call this process episodic memory formation: the locking of ideas and objects to a single place and time, to forming associations between different stimuli.
Using a a new process that involves an injected virus and a chemical “remote control for the brain,” psychologists are now a little closer to understanding it better.
Researchers at Dartmouth and the University of North Carolina announced Tuesday that new evidence indicates that the retrosplenial cortex—a little-studied region near the center of the brain—is important in the formation of this kind of information, called episodic memories. Specifically, they believe the retrosplenial cortex may help make sense of the burst of new stimuli in a new environment: It may be the place where the body’s senses are integrated....

I have a 3 year, (maybe more,) timespan extending from onset (depressive symptoms), worsening through the middle then lessening as... things slowly improved, where I don't really have chronology (no readily recallable episodic memory.) Merely events disconnected, organized in the roughest way - by place, usally by the rooms in which I slept. Representations without any, nearly, personal affect....
