AIMS This study was designed to evaluate the changes in EEG power spectra and EEG coherence in a ketamine model of psychosis in rats. Analyses of behavioral measurements--locomotion and sensorimotor gating--and the pharmacokinetics of ketamine and norketamine were also conducted. METHODS Ketamine and norketamine levels in rat sera and brains were analyzed(More)
Behavioral, neurochemical and pharmaco-EEG profiles of a new synthetic drug 4-bromo-2,5-dimethoxyphenethylamine (2C-B) in rats were examined. Locomotor effects, prepulse inhibition (PPI) of acoustic startle reaction (ASR), dopamine and its metabolite levels in nucleus accumbens (NAc), EEG power spectra and coherence in freely moving rats were analysed.(More)
Despite poisoning with the ecstasy substitute para-methoxymethamphetamine (PMMA) being typically associated with severe hyperthermia and death, behavioral and toxicological data on this drug are missing. Herein we present the behavioral profile of PMMA, its hyperthermic potency and pharmacokinetic profile in rats. The effects of PMMA 5 and 20 mg/kg on(More)
Perinatal immune challenge leads to neurodevelopmental dysfunction, permanent immune dysregulation and abnormal behaviour, which have been shown to have translational validity to findings in human neuropsychiatric disorders (e.g. schizophrenia, mood and anxiety disorders, autism, Parkinson's disease and Alzheimer's disease). The aim of this animal study was(More)
In the present study we investigated the potential antipsychotic effects of the mGlu2/3 agonist LY379268 on changes in EEG power spectra and coherence in the ketamine model of psychosis. In order to use behaviorally active drug doses, experiments detecting changes in locomotor activity and sensorimotor gating were also conducted. In EEG experiments, adult(More)
