Effects of chronic stress on nicotine-induced locomotor activity and corticosterone release in adult and adolescent rats
(Addiction Biology, 2008-03-01) [Artigo]
We examined nicotine-induced locomotion and increase in corticosterone plasma levels in adolescent and adult animals exposed to chronic restraint stress. Adolescent [postnatal day (P) 28-37] and adult (P60-67) rats were ...
Matemal separation affects cocaine-induced locomotion and response to novelty in adolescent, but not in adult rats
(Brain Research, 2004-07-02) [Artigo]
Maternal separation is known to exert long-term effects on both behavior and the neuroendocrine system. We investigated cocaine-induced locomotor activation as well as the locomotor and corticosterone response to forced ...
Differential behavioral and neuroendocrine effects of repeated nicotine in adolescent and adult rats
(Pharmacology Biochemistry and Behavior, 2005-03-01) [Artigo]
Despite the high prevalence of tobacco abuse among adolescents, the neurobiology of nicotine addiction has been studied mainly in adult animals. Repeated administration of this drug to adult rats induces behavioral ...
Chronic restraint or variable stresses differently affect the behavior, corticosterone secretion and body weight in rats
(Physiology & Behavior, 2007-01-30) [Artigo]
Organisms are constantly subjected to stressful stimuli that affect numerous physiological processes and activate the hypothalamo-pituitary-adrenal (HPA) axis, increasing the release of glucocorticoids. Exposure to chronic ...
Repeated predictable or unpredictable stress: effects on cocaine-induced locomotion and cyclic AMP-dependent protein kinase activity
(Behavioural Brain Research, 2003-02-17) [Artigo]
Stressful experiences appear to have a strong influence on susceptibility to drug taking behavior. Cross-sensitization between stress and drug-induced locomotor response has been found. Locomotor response to novelty or ...
