Some individuals exposed to traumatic experiences develop anxiety problems including posttraumatic stress disorder and exhibit deficient regulation of fear responses. Experimental models such as rodent extinction of conditioned fear have been created to study the mechanisms underlying fear regulation. Extinction entails mastering to inhibit worry reactions to a stimulus that has been previously paired with an aversive stimulus like a mild electrical shock. Research in both humans and rodents show that interactions amongst the amygdala, hippocampus, and infralimbic prefrontal cortex (IL) are significant for worry extinction mastering and memory (Quirk and Mueller, 2008; Pape and Pare, 2010; ?Milad and Quirk, 2012; Orsini and Maren, 2012). During the recall of fear extinction, it’s proposed that IL inhibits worry by minimizing activity outflow from the amygdala (Quirk et al., 2003), a structure essential for finding out and expressing worry memories (Phelps and LeDoux, 2005; Schafe et al., 2005). In order for IL toReceived Nov. 7, 2012; revised Feb. 1, 2013; accepted Feb. 27, 2013.
