Implication of orexin transmission in chronic stress, hyperarousal, and neuroplasticity deficits: a mechanistic framework for depression and anxiety
Stress is a major risk factor for depression- and anxiety-related disorders and produces neuroplastic adaptations within brain regions that regulate emotion, cognition, and stress responsivity. These adaptations include dendritic retraction in the medial prefrontal cortex (mPFC), suppression of plasticity and neurogene...
