Spatial guidance of choice behavior in the radial-arm maze.
In 6 experiments, the performance of male rats in a 12-arm radial maze was examined. The focus of study was the extent to which the spatial location of individual baited maze arms was determined before the rat was exposed to the extramaze visual cues corresponding to the arm, and thereby guided the rat toward the location of baited arms. Such spatial guidance of choice behavior implies a spatia...
متن کاملWithin-Trial Dynamics of Radial Arm Maze Performance in Rats
The behavior of rats white solving a 12-arm radial maze was investigated using measures of response bias, choice latencies, and behavioral organization. Response bias decreased as a function of choice number, while the amount of time spent on the center platform between choices increased substantially during the last few choices. This increase in time between choices was largely accounted for b...
متن کامل3,4 methylenedioxymethamphetamine (ecstasy) impairs eight-arm radial maze performance and arm entry pattern in rats.
The recreational use of 3,4 methylenedioxymethamphetamine (ecstasy) in humans has been associated with memory impairment. The present study examined whether ecstasy impairs short- and long-term working memory and the pattern of arm entries in rats tested in the 8-arm radial maze with a 2-hr delay. After completing the training session, the rats were given a single dose of ecstasy (1, 2, or 3 mg...

متن کاملIntegration of olfactory information in a spatial representation enabling accurate arm choice in the radial arm maze.
The aim of the present study was to determine whether and how rats can use local olfactory cues for spatial orientation. Rats were trained in an eight-arm radial maze under different conditions as defined by the presence or absence of supplementary olfactory cues marking each arm, the availability of distant visuospatial information, and the illumination of the maze (light or darkness). The dif...
