In the present study, the effects of bilateral injections of cholinergic agents into the hippocampal CA1 regions (intra-CA1) on ethanol state-dependent memory were examined in mice. A single-trial step-down passive avoidance task was used for the assessment of memory retention in adult male NMRI mice. Pre-training intraperitoneal injection (i.p.) of ethanol(More)
In the present study, the effects of repeated intra-ventral hippocampal (intra-VH) microinjections of nicotinic acetylcholine receptor agonist or antagonist on morphine-induced anxiolytic-like behavior were investigated in morphine-sensitized mice using elevated plus-maze. Intraperitoneal (i.p.) administration of different doses of morphine (5, 7.5 and(More)
The present study evaluated the involvement of the dorsal hippocampal cannabinoid CB1 receptors in the combined effect of ethanol and nicotine on passive avoidance learning in adult male mice. The results indicated that pre-training administration of ethanol (1 g/kg, i.p.) impaired memory retrieval. Pre-test administration of ethanol (0.5 and 1 g/kg, i.p.)(More)
Experiencing early-life stress has been considered as a potent risk factor for the development of many of brain disorders, including seizures. Intervening mechanisms through which neonatal maternal separation (MS) alters the seizure susceptibility in adulthood have not been well studied. In the current study, by applying 180 min of MS stress (PND 2-14), we(More)
The present study examined whether nicotinic acetylcholine receptors (nAChRs) of the CA1 regions of the dorsal hippocampus and medial septum (MS) are involved in cross state-dependent memory retrieval between WIN55, 212-2 (WIN, a non-selective CB1/CB2 receptor agonist) and nicotine or ethanol. Memory retrieval was measured in one-trial step-down type(More)
Early-life stress adversely affects the development of the brain, and alters a variety of behaviors such as pain in later life. In present study, we investigated how early-life stress (maternal separation or MS) can affect the nociceptive response later in life. We particularly focused on the role of oxytocin (OT) in regulating nociception in previously(More)
Amphetamine withdrawal (AW) is accompanied by diminished pleasure and depression which plays a key role in drug relapse and addictive behaviors. There is no efficient treatment for AW-induced depression and underpinning mechanisms were not well determined. Considering both transient receptor potential cation channel, subfamily V, member 1 (TRPV1) and(More)
Mother-infant interactions are known to be associated with the psychological well-being of an individual in adulthood. It is well accepted that emotional stress in early life, such as maternal separation (MS), leads to alterations in the neurotransmission systems of various brain regions, especially the mesolimbic dopaminergic system, and subsequently can(More)
The aim of the current study was to examine the effect of dorsal hippocampal nicotinic acetylcholine receptors (nAChRs) activation on the functional interaction between ethanol and 3,4-methylenedioxy-N-methylamphetamine (MDMA or ecstasy) in memory retrieval. The dorsal hippocampal CA1 regions of adult male NMRI mice were bilaterally cannulated and memory(More)
Histamine regulates release of neurotransmitters such as dopamine, serotonin, gamma-aminobutyric acid (GABA), glutamate and also is involved in several functions in central nervous system (CNS). It has been shown that histamine participates in disorders like seizure. It has been well documented that morphine dose-dependently induces anti or proconvulsant(More)
