Dopamine regulates reward-related behavior through the mesolimbic dopaminergic
pathway. Stress affects dopamine levels and dopaminergic neuronal activity in the …

Previous work in animals has shown that dopamine (DA) in cortex and striatum plays an
essential role in stress processing. For the first time, we systematically reviewed the in vivo …

Highlights•Stress preferentially perturbates reward anticipation (rather than
consumption).•Cortico–striatal–limbic network dysregulation subserves stress effects on …

In this review, we will examine the most recent preclinical evidence in support of the fact that
both acute and chronic stress may have a detrimental impact on the normal function of the …

Although, historically, the norepinephrine system has attracted the majority of attention in the
study of the stress response, the dopamine system has also been consistently implicated. It …

The response of the central nervous system to stress is often critical to the adaptation of an
organism to its environment. However, in humans the response to stress also can be …

Accumulating evidence shows that stressful events evoke molecular alterations in the brain,
considered a pathology in major depressive disorder (MDD). However, the abnormalities of …

Exposure to either restraint or footshock (3–60 min) induced similar biphasic alterations of 3-
methoxytyramine (3-MT) concentrations (initial increase followed by decrease below control …

The present review was aimed at re-evaluating results obtained from animal models of
depression based on experimental stressors in the light of the most recent data on the …

Stressors can exert a wide variety of responses, ranging from adaptive responses to
pathological changes; moreover, recent studies suggest that mild stressors can attenuate …
