Post-traumatic stress disorder has been linked to the dopamine, norepinephrine, endorphin, serotonin, and oxytocin systems, as well as the mesocortical and mesolimbic dopamine, norepinephrine, endorphin, serotonin, and oxytocin systems. On the other hand, very little is known about how these different systems interact, and no well-known unified theory has yet emerged. This review suggests that galanergic suppression of dopaminergic neurons in the ventral tegmental might be the missing link in a post-traumatic feedback loop.
