The effect of post-training intradorsal striatal infusion of metabotropic glutamate receptor (mGluR) drugs on memory consolidation processes in an inhibitory avoidance (IA) task and visible/hidden platform water maze tasks was examined. In the IA task, adult male Long-Evans rats received post-training intracaudate infusions of the broad spectrum mGluR antagonist alpha-methyl-4-carboxyphenylglyc...
2-Deoxy-D-glucose (2DG), a glucose analog that transiently inhibits glycolysis, has anticonvulsant and antiepileptic disease-modifying properties in experimental in vivo models of seizures and epilepsy. Here we evaluated the effects of 2DG across the range of doses (50-500mg/kg i.p.) shown previously to exert anticonvulsant and antiepileptic effects in rats, on spatial learning and memory using...
The mammalian hippocampus continues to generate new neurons throughout life. Experiences such as exercise, anti-depressants, and stress regulate levels of neurogenesis. Exercise increases adult hippocampal neurogenesis and enhances behavioral performance on rotarod, contextual fear and water maze in rodents. To directly test whether intact neurogenesis is required for gains in behavioral perfor...
Damage to the hippocampus typically produces temporally graded retrograde amnesia, whereby memories acquired recently are impaired more than memories acquired remotely. This phenomenon has been demonstrated repeatedly in a variety of species and tasks, and it has figured prominently in theoretical treatments of memory and hippocampal function. A striking exception to the finding of temporally g...
Spatial and contextual learning are considered to be dependent on the hippocampus, but the extent to which other structures in the medial temporal lobe memory system support these functions is not well understood. This study examined the effects of individual and combined lesions of the perirhinal, postrhinal, and entorhinal cortices on spatial and contextual learning. Lesioned subjects were co...
BACKGROUND In Japan, the effects of reduced water, such as hydrogen-rich electrolyzed reduced water and natural reduced water, like Hita Tenryosui water®, have been examined. The purpose of the present study was to identify the role of natural reduced water in anxiety and blood biochemical analysis. MATERIALS AND METHODS Natural reduced water and distilled water were administered to rats for ...
The Morris water maze, a spatial learning task first introduced by Dr. Richard Morris (Morris, 1981, 1984), is one of the most extensively used behavioral paradigms used to examine hippocampus-dependent spatial learning and memory in rodents, such as rats and mice (Tanda et al., 2009). In water maze tests, animals are forced to swim in a circular pool of milky water. In order to escape from the...
nitric oxide (no) is thought to be involved in spatial learning and memory in several brain areas such as hippocampus. this study examined the effects of post-training intrahippocampal microinjections of 1400w as a selective inducible nitric oxide synthase (inos) inhibitor on spatial memory, in both anesthetized and non-anesthetized situations in rats. in the present work, 4-day training trials...
Lurcher mutant mice represent a model of genetically determined olivocerebellar degeneration. In the C3H strain there is also hereditary retinal degeneration. The aim of this work was to assess, whether the retinal degeneration influences spatial orientation and results of the spatial learning tasks. Two experiments in the Morris water maze were arranged. First, mice learned to find a platform ...
This study aimed to investigate the hypoglycemic, lipid-lowering and antidepressant effects of Zuogui Jiangtang Jieyu formulation (ZGJTJY) in a model of unpredictable chronic mild stress (UCMS) in rats with diabetes mellitus (DM; the UCMS-DM model). Sixty rats were randomly divided into blank control, vehicle (model plus vehicle), positive control (model plus metformin and fluoxetine), and high...
