Figure 6:

Socioeconomic and Environmental Stressors vs. Stress-Associated Neurobiological Activity and CVD Events.

Individuals were categorized according to quartiles of neighborhood median income and transportation noise exposure. Amygdalar activity decreased as neighborhood median income increased (A) and increased as transportation noise exposure increased (B). Error bars represent standard error of the mean. Similarly, CVD event-free survival was lower among individuals with lower neighborhood income (C) or higher chronic noise exposure (D, >55 dBA, a level deemed unhealthy by the World Health Organization).
