Stress-induced cross-sensitization to amphetamine is related to changes in the dopaminergic system
(Journal of Neural Transmission, 2012-04-01) [Artigo]
Repeated stress engenders behavioral sensitization. The mesolimbic dopamine system is critically involved in drug-induced behavioral sensitization. In the present study we examined the differences between adolescent and ...
Repeated administration of caffeine induces either sensitization or tolerance of locomotor stimulation depending on the environmental context
(Pharmacological Reports, 2012-01-01) [Artigo]
Caffeine is the psychostimulant substance consumed in greatest quantities in the world. The repeated administration of psychostimulants can either decrease or increase the drug effect, inducing tolerance or sensitization, ...
Behavioral and neuroendocrine effects of the exposure to chronic restraint or variable stress in early adolescent rats
(International Journal of Developmental Neuroscience, 2012-02-01) [Artigo]
Stress events during adolescence may contribute to the expression or exacerbation of physical and behavioral disorders. However, little attention has been given to the physiological and behavioral changes promoted by stress ...
Stress induces behavioral sensitization, increases nicotine-seeking behavior and leads to a decrease of CREB in the nucleus accumbens
(Pharmacology Biochemistry and Behavior, 2012-05-01) [Artigo]
Experimental evidence shows that exposure to stress engenders behavioral sensitization and increases drug-seeking and leads to intense drug taking. However the molecular mechanisms involved in these processes is not well ...
Effects of simultaneous exposure to stress and nicotine on nicotine-induced locomotor activation in adolescent and adult rats
(Brazilian Journal of Medical and Biological Research, 2012-01-01) [Artigo]
Preclinical studies have shown that repeated stress experiences can result in an increase in the locomotor response to the subsequent administration of drugs of abuse, a phenomenon that has been termed behavioral ...
