Likewise, in science chaos describes a physical
system whose
behavior is unpredictable and whose
final state is extremely sensitive to initial conditions.
The costs associated with this
final rule involve, for each provision, consideration of both the degree to which covered entities must modify their existing records management
systems and privacy policies under the
final rule, and the extent to which there is a change in
behavior by both patients and the covered entities as a result of the
final rule.
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
