(A) There were no significant running distance differences between animals in rats exposed to exercise prior to extinction (Pre), immediately post extinction (Post), 6 h post extinction (Post 6 h). (B) Running distance and correlation of distance (m) to mean percent freezing at test. It was demonstrated that running distance was positively correlated with freezing, which indicated that greater running distances lead to increased levels of freezing, indicative of enhanced memory acquisition or consolidation.
