introduction: the influence of ascorbic acid on the nicotine-induced conditioned place preference (cpp) and behavioral sensitization was investigated in the present study. methods: in a pilot study, place conditioning and locomotor activity were investigated after nicotine (0.25, 0.5, 0.75, 1, 1.5 and 2 mg/kg) or ascorbic acid (1, 10, 100 and 1000 mg/kg) administration. different doses of ascor...
The rewarding effects of nicotine contribute to the chronic use of tobacco products. The place conditioning task, a widely used pre-clinical model to study drug reward, has lead to mixed results in rats when nicotine was administered subcutaneously or intraperitoneally; intravenously administered nicotine has not been examined. Further, much of the research demonstrating a nicotine-conditioned ...
Objective: The effect of linalool, a terpene alcohol found in many plants, which inhibits NMDA receptors, on the acquisition and reinstatement of morphine-induced conditioned place preference (CPP) was evaluated in mice.Material and Methods: The effects of different doses of linalool (12.5, 25 and 50 mg/kg, i.p.), memantine (20 mg/kg, an NMDA receptor antagonist) and saline, in CPP induced by 4...
Background and Aim: The hippocampus is a region of the brain that plays an important role in learning activities, including conditioned place preference (CPP). This area is widely used as the target of the studies on the reinforcing effects of the drugs and narcotics. Considering the wide distribution of GABAB receptors in the hippocampus CA1 region, these receptors are likely to play an import...
Introduction: Dependence on morphine and its complications are considered as a major health problem in the world; however, efforts to overcome this problem have failed due to the severity of drug dependence. Amygdala core nucleus (CeA) is one of the most important areas affecting the effects of morphine rewards. The GABAergic system in this nucleus; especially the GABAB receptors plays an impor...
In the present study we examined the effect of MPEP [2-methyl-6-(phenylethynyl)-pyridine] a potent, selective and systemically active metabotropic glutamate receptor (mGluR) type I (subtype mGluR5) antagonist on conditioned morphine reward in mice. In an unbiased version of conditioned place preference (CPP) paradigm, single conditioning with 10 mg/kg of morphine produced reliable place prefere...
The effects of intra-accumbens sulpiride on conditioned place preference and locomotion produced by i.v. cocaine were investigated. Every other day during conditioning, rats received infusions of sulpiride (0-0.4 microgram) into the nucleus accumbens (NAc) or caudate-putamen. Fifteen min later, they were placed into a distinct compartment and injected with saline or cocaine (4.2 mg/kg, i.v.). O...
Introduction: The influence of ascorbic acid on the nicotine-induced conditioned place preference (CPP) and behavioral sensitization was investigated in the present study. Methods: In a pilot study, place conditioning and locomotor activity were investigated after nicotine (0.25, 0.5, 0.75, 1, 1.5 and 2 mg/kg) or ascorbic acid (1, 10, 100 and 1000 mg/kg) administration. Different doses of a...
INTRODUCTION A close interaction exists between the brain opioid and serotonin (5-HT) neurotransmitter systems. Brain neurotransmitter 5-HT plays an important role in the regulation of reward-related processing. However, a few studies have investigated the potential role of 5-HT2A receptors in this behavior. Therefore, the aim of the present study was to assess the influence of morphine and Con...
