Chronic intermittent hypoxia (CIH)-induced noradrenergic dysregulation is associated to increased disinhibitory dopamine activity in the paraventricular nucleus of the thalamus (PVT). Secondly, chronic hypoxic stress may increases cortisol production through a disinhibitory reuptake mechanism associated with a locus coeruleus (LC-NE)-mediated rise in extracellular dopamine levels in the dorsal striatum. Consequently, chronic intermittent hypoxia (CIH) may enhances stress-dependent cortisol responses (c-Fos expression) in the striatum through dopaminergic projections from the locus coeruleus.
