One final example is the prefrontal cortex, which is thought to play an important role in regulating behavior by suppressing impulses and emotions arising from the amygdala and other parts of the limbic system.50 — 52 In animal studies, exposure to chronic stress or glucocorticoids alters the synaptic connectivity within the prefrontal cortex, 52,53 and this may limit the ability of the prefrontal cortex to (1) suppress the impulsivity and aggression of the limbic system, and (2) execute adaptive responses (rather than maladaptive responses) to stress.54 — 56 Stress - induced changes in brain structure parallel the well - described impact of significant childhood adversity on a variety of brain functions, including the modulation of physiologic responses (hyper - responsive or chronically active stress response), learning (impaired memory), and the regulation of behavior (the ability to execute adaptive vs maladaptive responses to stress).3, 39,57
