Adenosine receptor ligands and cocaine in conditioned place preference (CPP) test in rats.
The influence of adenosine receptor agonists and antagonists on cocaine--induced conditioned place preference (CPP) was examined in male Wistar rats. Adenosine receptor agonists, when given alone, induced place preference in some dose ranges, and it seems that adenosine A1 and A2 receptors might be involved in this reaction. All adenosine receptor agonists: 2-p-(2-carboxyethyl)phenethylamino-5'...
متن کامل[Electroacupuncture suppresses morphine--induced conditioned place preference (CPP) in rats].
OBJECTIVE To examine the effects produced by electroacupuncture (EA) of different frequencies on the expression of morphine conditioned place preference (CPP) in rats. METHODS SD rats were given 4 days consecutive trials in a computerized three-chamber "unbiased" CPP apparatus. Twenty-four hours later, the time spent on drug-pairing compartment of the rat was examined. Rats trained with CPP p...
متن کاملIntravenous cocaine priming reinstates cocaine-induced conditioned place preference
Separate groups of rats underwent an unbiased conditioned place preference (CPP) procedure involving alternate pairings of distinct environments with intravenous (IV) injections of cocaine (.75 mg/kg) or saline immediately or 15 min after injection. A subsequent extinction phase consisted of exposure to both conditioning environments preceded by saline injection (Ext). Finally, an IV priming in...
متن کاملThe NMDA antagonist MK-801 disrupts reconsolidation of a cocaine-associated memory for conditioned place preference but not for self-administration in rats.
Recent research suggests that drug-related memories are reactivated after exposure to environmental cues and may undergo reconsolidation, a process that can strengthen memories. Conversely, reconsolidation may be disrupted by certain pharmacological agents such that the drug-associated memory is weakened. Several studies have demonstrated disruption of memory reconsolidation using a drug-induce...
متن کاملTrkB signaling is required for behavioral sensitization and conditioned place preference induced by a single injection of cocaine
Exogenous brain-derived neurotrophic factor (BDNF) can regulate behavioral sensitization and conditioned place preference (CPP) when animals are exposed to repeated cocaine administration. However, it is unclear whether BDNF signaling through the TrkB receptor can mediate these behavioral responses when animals are given a single cocaine exposure. Because TrkB knockout mice die as neonates, we ...
