Both the hypothalamus-pituitary-adrenal (HPA) axis and the extrahypothalamic brain stress system are key elements of the neural circuitry that regulates the negative states during abstinence from chronic drug exposure. Orexins have recently been hypothesized to modulate the extended amygdala and to contribute to the negative emotional state associated with(More)
Different neurotransmitter systems are involved in behavioural and molecular responses to morphine. The brain stress system is activated by acute administration of drugs of abuse, being CRF the main neuropeptide of this circuitry. In this study we have studied the role of CRF1R in the rewarding effects of morphine using the CPP paradigm. For that, animals(More)
