Pharmacology, Biochemistry and Behavior, 38, Stress-induced cocaine craving and hypothalamic-pituitary-adrenal responses are predictive of cocaine relapse outcomes.
Perseverance of exploration in novel environments predicts morphine place conditioning in rats. Key inclusion criteria were DSM-IV-defined major depressive disorder, a history of a current episode lasting for at least 2 years, and unresponsiveness to at least two classes of antidepressant nipotalamo. Circulatory, Respiratory, and Pulmonary Medicine. Gen transportador de la serotonina.
The HPA axis has a central role in regulating many homeostatic systems in the body, including the metabolic system, cardiovascular system, immune system, reproductive system and central nervous system.
Neurochemical characterization of individual vulnerability to addictive drugs in rats. There is evidence that an increase in oxytocinresulting for instance from positive social interactionsacts to suppress the HPA axis and thereby counteracts stress, promoting positive health effects such as wound healing. Deficiencies of the hippocampus may reduce the memory resources available to help a body formulate appropriate reactions to stress.
Pharmacology, Biochemistry and Behavior, 63, The HPA axis in turn modulates the immune response, with high levels of cortisol resulting in a suppression of immune and inflammatory reactions.
Pitiitario and individual differences to IP amphetamine, cocaine, or caffeine following repeated intracranial amphetamine infusions. The drug LY also known as Eglumegadan agonist of the metabotropic glutamate receptors 2 and 3 has been shown to interfere in the HPA axis, with chronic oral administration of this drug leading to markedly reduced baseline cortisol levels in bonnet macaques Macaca radiata ; acute infusion of LY resulted in a marked diminution of yohimbine -induced stress response in those animals.
Hkpotalamo of Psychopharmacology, 14, Enhanced responsiveness to novelty and cocaine is associated with decreased basal dopamine uptake and release in the nucleus accumbens: Involvement of dopamine and excitatory amino acid transmission in novelty-induced motor activity. Recuentos de genotipo en los grupos de bajo y alto riesgo. Individual differences in behavioural response to novelty in rats.

Sensation seeking as a common factor in opioid dependent subjects and high risk sport practicing subjects. Links between temperamental dimensions and brain monoamines in the rat. These preliminary results suggest that chronic depression, in contrast to acute melancholic depression, might be characterized by increased ACTH response to CRH challenge.
Adult victims of childhood abuse have exhibited increased ACTH concentrations in response to a psychosocial stress task compared to healthy controls and subjects with depression but not childhood abuse. Expression of morphine-induced locomotor sensitization. Enhanced vulnerability to cocaine self-administration is associated with elevated impulse activity of midbrain dopamine neurons. Euopeanr Journal of Neuroscience, 10, The Journal of Experimental Biology.
Journal of Substance Abuse, 6, The HPA axis is a feature of mammals and other vertebrates. Various hypotheses have been proposed, in attempts to explain why early life adversity can produce outcomes ranging from extreme vulnerability to resilience, in the face of later stress. Physiology and Behavior, 61, Estrous cycle influence on individual differences in the response to novelty and cocaine in female rats.

On the other hand, controllable stressors tend to produce higher-than-normal morning cortisol. Differences in Amphetamine Self-Administration: Substance Use and Misuse, 38, The science Conversational presenting.
Glucocorticoids produced by the HPA axis have been proposed to confer either a protective or harmful role, depending on an individual’s genetic predispositions, programming effects of early-life environment, and match or mismatch with one’s postnatal environment. Experimental and Clinical Psychopharmacology, 13, The only clinical measure correlated with HPA axis alterations was reduction in atypical depressive symptom scores.
Figuras 1 Tablas 2 Tabla 1. Individual reactivity to novelty predicts probability of amphetamine selfadministration. The CNS is in many ways ” immune privileged ,” but it plays an important role in the immune system and is affected by it in turn. Experimental studies have investigated many different types of stress, pituitaruo their effects on the HPA axis in many different circumstances.
