Repeated administration of nicotine causes incentive and behavioral sensitization in animals. Ascorbic acid administration inhibits some effects of nicotine. In the present study, the effect of ascorbic acid administration on nicotine-induced behavioral sensitization in Male Swiss-Webster mice (20-25 g) was investigated. Animals were injected with nicotine (0.25 mg/kg, i.p.) once daily for seve...

The paper deals with the involvement of endocannabionid brain system in dopamine mechanisms of behavioural sensitization to psychostimulants. The development and manifestation of behavioural sensitization to methamphetamine are described. Results obtained in our previous studies, showing an interaction between the endocannabinoid system and methamphetamine brain mechanisms, in the rat intraveno...

The presentation of novel, remarkable, and unpredictable tastes increases dopamine (DA) transmission in different DA terminal areas such as the nucleus accumbens (NAc) shell and core and the medial prefrontal cortex (mPFC), as estimated by in vivo microdialysis studies in rats. This effect undergoes adaptive regulation, as there is a decrease in DA responsiveness after a single pre-exposure to ...
