sup][26] The Y-maze spontaneous alternation task is based on the fact that rodents have a natural tendency of exploring a novel environment, which need to use visual recognition or spatial working memory, which is hippocampus-dependent.
Quantity or scope: This contract is for the supply, delivery, installation and commissioning for operation of equipment specific to the study of animal behavior (Morris water maze, Y-maze, T-maze, Elevated More Maze Open Field, Rotarod type of system of & lt maze; & lt; Place Preference > & gt ;, 2 bedrooms of fear conditioning and 4 cages operating) for the School of Neurosciences of the University of Bordeaux.
Opposite to this, other findings suggest that some antidepressants such as fluoxetine, venlafaxine can impair the spatial memory in a variant of Y-maze test in rats (which are not capable to recognise the arm with changed brightness), while reboxetine does not significant interfere the animal spatial memory performance in the same behavioural model, probably due to the lack of influence on the serotonin level (17).
In order to determine the period of drug treatment after OVX surgery, we evaluated the effect of ovariectomy on learning and memory activities in different periods (4 and 8 weeks) after surgery using Y-maze test at first, in preliminary experiments.
We are also grateful to Ron Moore, Rob Deanes, and Troy Alphin for help with Y-maze setup, to Brad Parnell and Dana Friend for help with monitoring handling time trials, and to the Benthic Lab at the University of North Carolina Wilmington for providing salinity and water temperature data (www.
Experiments were done inside a windowless, dark room that housed the Y-maze.
The odor preferences of individual female mice were tested in a translucent Plexiglas Y-maze apparatus with two arms and three chambers (Figure 1).
These animals were tested in a Y-maze olfactometer to determine if there was any preference shown toward certain odor cues.
In addition, in these animal models, we could test the main cognitive deficits of the autism pathology, by using several important behavioural tasks in rat (mainly used for the memory determinations): step-through passive avoidance task, active avoidance task, Y-maze or T-maze tasks (8), etc.
Lancemaside A and echinocystic acid significantly reversed scopolamine-induced memory and learning deficits on the Y-maze and Morris water maze tasks.
Laboratory experiments in y-maze tubes showed that starved sea urchins responded on tree different baits in about one minute, but they did not discriminate between offal of fish (saithe), sea urchin fodder, and lamina of kelp.
