      - increased volume in medial prefrontal cortex
- - - - epinephrine release from adrenal glands
      - production of immediate fight-flight responses
    - - release of corticotropic-releasing hormone (CRH) & vasopression
      - anterior pituitary gland releases, adrenocorticotrophic hormone (ACTH) into circulation
      - ACTH stimulates release of cortisol by the adrenal glands
      - Excess cortisol is neurotoxic
      - hippocampus inhibits CRH release in response to high cortisol levels
