FIG. 5.
Stress-induced dendritic remodeling and alterations in mushroom spine density correlate with extinction deficits. (A) Linear regression for average basolateral amygdala (BLA) branch number for unstressed (black dots; n = 8) and stressed (gray dots; n = 10) rats vs. percentage freezing during extinction (averaged across trials). (B) Linear regression for average BLA dendritic length for unstressed (black dots) and stressed (gray dots) rats vs. percentage freezing during extinction (averaged across trials). (C) Linear regression for average mushroom spine density on third-order and fourth-order branches for unstressed (black dots) and stressed (gray dots) rats vs. percentage freezing during extinction (averaged across trials).
