Repeated treatment with fluoxetine and citalopram, which are potent 5-HT reuptake inhibitors, resulted in different regulation of 5-HT1A and 5-HT2 receptors in the rat brain. Their effects were compared with those of other antidepressants: imipramine, mianserin and levoprotiline. The density of 5-HT1A receptors, labelled with [3H]8-OH-DPAT, in the rat(More)
Exposure of alcohol addicts to alcohol-related environmental cues may elicit alcohol-seeking behavior and lead to relapse to heavy drinking. The aim of the present study was to identify brain regions activated by alcohol (ethanol)-related stimuli in Wistar rats trained to lever press for 8% ethanol solution in operant self-administration cages. Ethanol(More)
AMPA receptor activation has been demonstrated to increase the neuronal expression of brain derived neurotrophic factor (BDNF). In the present study, we investigated the effect of a novel AMPA receptor potentiator (LY404187) and its active isomer (LY451646) on the expression of BDNF protein and mRNA, as well as TrkB mRNA in rat hippocampus. LY404187(More)
The malfunction of glutamatergic neurotransmission in the neonatal or postnatal periods may be a risk factor for the appearance of neuroanatomical, neurochemical or functional changes that are characteristic of schizophrenia. Thus, the present study was undertaken to investigate whether blockade of N-methyl-d-aspartate (NMDA) receptors in the postnatal(More)
Interest in kainate receptors has increased over the past few years. Our understanding of their physiology and pharmacology has improved markedly since their original cloning and expression in the early 1990s. For example, agonist profiles at recombinant kainate receptors have been used to identify and distinguish kainate receptors in neurons. Furthermore,(More)
The hallucinogenic effect of DOI, serotonin 5-HT2A/2C receptor agonist, is known to be associated with the activation of cortical 5-HT2 receptors. However, the effect of DOI on excitability of cortical neurons and their subsequent function is still not quite understood. Previous immunohistochemical studies using Fos proteins expression as a marker of(More)
