Application of a novel Active Allothetic Place Avoidance task (AAPA) in testing a pharmacological model of psychosis in rats: comparison with the Morris Water Maze
Original language description
Administration of a non-competitive NMDA antagonist dizocilpine (MK-801) was proposed to be an animal model of psychosis. However, the role of NMDA-receptors in organizing brain representations is not understood yet. We tested the effect of NMDA-receptorblockade by systemic administration of dizocilpine at two different doses (0.1 mg/kg or 0.2 mg/kg) in a recently designed Active Allothetic Place Avoidance, a task which requires rats to separate spatial stimuli from two continuously dissociated subsets. The effect of dizocilpine on learning in the AAPA task was compared with its effect on acquisition of the reference memory version of the Morris Water Maze task. Both doses impaired performance in the Morris Water Maze task, whereas only the higher dose impaired performance in the AAPA task. The Morris Water Maze appears to be more sensitive to dizocilpine-induced behavioral deficit than the AAPA task

Použití nové úlohy aktivního alotetického vyhýbání se místu (AAPA) v testování farmakologického modelu psychózy: srovnáni s Morrisovým vodním bludištěm
Czech description
Aplikace nekompetitivních antagonistů NMDA receptoru se používá jako rozšířený model psychózy. Nicméně, role NMDA receptoru ve schopnosti organizovat prostorové informace do koherentních representací nebyla dosud testována. V této práci jsme studovali vliv aplikace 0.1 mg/kg a 0.2 mg/kg dizocilpinu na orientaci potkanů v úloze AAPA a v Morrisově vodním bludišti. V Morrisově vodním bludišti poškozovaly obě dávky účinnou orientaci, zatímco v úloze AAPA byla účinná pouze vyšší dávka. Morrisovo vodní bludiště se tedy zdá být účinnějším testem pro deficit navozený blokádou NMDA receptoru než úloha AAPA
