Addictive drugs share the properties of being self-administered by laboratory animals, and of activating the brain reward circuitry, which stems from the ventral tegmental area (VTA) where dopamine (DA) cells are located. These neurons are involved in neural processing contributing to drug addiction and DA plays a crucial role as learning ...

Activation of hypothalamo-pituitary-adrenal (HPA) axis is a common feature of endocrine responses to stress, with cortisol secretion as an end product of this activation. Acute rise in cortisol level during stress is of utmost importance for metabolic adjustments, immune system adaptations, cardiovascular responses and muscle tissue remodeling. But since chronic hypercortisolism has many deleterious effects, scientific interest has started focusing around different biological ...
