The Brain on Stress: Vulnerability and Plasticity of the Prefrontal Cortex over the Life Course

Open access
McEwen, Bruce S., Morrison, John H.·2013·Neuron

Abstract

The prefrontal cortex (PFC) is involved in working memory and self-regulatory and goal-directed behaviors and displays remarkable structural and functional plasticity over the life course. Neural circuitry, molecular profiles, and neurochemistry can be changed by experiences, which influence behavior as well as neuroendocrine and autonomic function. Such effects have a particular impact during infancy and in adolescence. Behavioral stress affects both the structure and function of PFC, though such effects are not necessarily permanent, as young animals show remarkable neuronal resilience if the stress is discontinued. During aging, neurons within the PFC become less resilient to stress. There are also sex differences in the PFC response to stressors. While such stress and sex hormone-related alterations occur in regions mediating the highest levels of cognitive function and self-regulatory control, the fact that they are not necessarily permanent has implications for future behavior-based therapies that harness neural plasticity for recovery.

  • In rodents, the most abundant and consistent changes in chronic stress models are in the medial prefrontal cortex, including anterior cingulate, prelimbic, and infralimbic regions, with somewhat more variable, mixed direction effects in the orbitofrontal cortex.

    “In rodents, the most abundant and consistent changes are in the mPFC (anterior cingulate, prelimbic and infralimbic) with somewhat more variable, mixed direction effects in the OFC (Fig. 3, top left-hand panel).”

  • Accompanying behavioral changes in chronic stress models are marked physiological and structural alterations in the amygdala, hippocampus, and prefrontal cortex that are similar to those seen in major depressive disorder.

    “Accompanying these behavioral changes are marked physiological and structural alterations, not only in the amygdala and hippocampus but, importantly, the PFC [98,99], that are similar to those seen in MDD.”

    From Prefrontal cortex and depression (2022) · cites this paper as [98]

    The “Effects of Stress on Prefrontal Cortex” section says repeated stress causes functional and structural changes in the PFC, amygdala, and hippocampus. “Relevance to human vulnerabilities and potential for brain plasticity” describes frontal-cortex and hippocampal changes in depressed individuals, but does not establish that the alterations across all three regions are similar to those in MDD. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The PFC likely regulates play in a multifactorial manner, contributing to expression of the behavior through its roles in suppressing aggression, monitoring approach/avoid conflict, and modulating the stress response via its projections to the MeA and other stress-modulatory nodes.

    “The PFC likely regulates play in a multifactorial manner, contributing to expression of the behavior through its roles in suppressing aggression, monitoring approach/avoid conflict, and modulating the stress response via its projections to the MeA and other stress-modulatory nodes (Aupperle & Paulus, 2010; McEwen & Morrison, 2013; Takahashi et al., 2014).”

  • Stress-induced structural changes in the PFC contribute to the pathophysiology of neuropsychiatric conditions.

    “Although stress-induced structural changes in the PFC are equally important in their contribution to the pathophysiology of neuropsychiatric conditions [256–262]”

    From Development of prefrontal cortex (2022) · cites this paper as [261]

  • Overwhelming evidence indicates PFC is uniquely important brain region for highest level of executive function, which drives self-regulatory and goal-directed behaviors.

    “Overwhelming evidence has indicated that PFC is a uniquely important brain region for the highest level of excecutive function, which drives self-regulatory and goal-directed behaviors 261–263.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
