Effects of intra-central amygdala administration of L-arginine, a nitric oxide precursor, and NG-nitro-L-arginine methyl-ester (L NAME), a nitric oxide synthase inhibitor, on the morphine-induced sensitization and also on the expression of morphine-induced place conditioning in rats were studied. Subcutaneous (s.c.) administration of morphine (2.5, 5 and 7.5 mg/kg) induced place conditioning. R...

this research was designed to study sexual differences in place conditioning induced by morphine in offspring born of female wistar rats mated with drug-naïve males. mothers were exposed to morphine during the 14th-16th days of gestational. control dams were simply saline-injected. female and male virgin offspring born of morphine-treated or saline-treated mothers were separately housed until b...
objective(s) single injection of naloxone, a selective antagonist of morphine, prior to the drug conditioning testing was used to investigate on morphine dependence. materials and methods conditioning to morphine (2.5-10 mg/kg, s.c.) was established in adult male wistar rats (weighing 200-250 g) using an unbiased procedure. nitric oxide agents were microinjected into the central amygdala prior ...

this review gives an overview of our recent findings and developments in research on brain mechanisms of morphine reward from studies using the place preference conditioning paradigm. intracranial place conditioning methodology has become a valuable and firmly established and very widely used tool in behavioural pharmacology and drug reward mechanisms. several studies have established that morp...

Encoding of behavioral episodes as spike sequences during hippocampal theta oscillations provides a neural substrate for computations on events extended across time and space. However, the mechanisms underlying the numerous and diverse experimentally observed properties of theta sequences remain poorly understood. Here we account for theta sequences using a novel model constrained by the septo-...
Recently, Spyraki et al. (Brain Research, 253 (1982) 195-203) reported that cocaine-induced place preference conditioning was unaffected by blockade of central dopamine (DA) or norepinephrine function. In addition, systemic injections of the local anesthetic procaine produced place preference conditioning. The present study was undertaken to further evaluate the possible role of DA in cocaine-i...
