3,4 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 کاملTime-place learning in the eight-arm radial maze.
Rats (n = 4) searched for food on an eight-arm radial maze. Daily 56-min sessions were divided into eight 7-min time zones, during each of which a different location provided food; locations were randomized across subjects before training. The rats obtained multiple pellets within each time zone by leaving and returning to the correct location. Evidence that the rats had knowledge about the tem...
متن کاملSpatial pattern learning in the radial arm maze.
Rats experienced a spatial pattern of baited and unbaited arms in an eight-arm radial maze. The spatial pattern remained constant over trials, but the spatial locations that were baited varied unpredictably. Although there was no evidence of control by the spatial pattern during free choice training trials, the rats' ability to locate baited arms in forced choice test trials was superior to tha...
متن کاملEffects of social facilitation for locating feeding sites by cattle in an eight-arm radial maze.
A study was conducted in an eight-arm radial maze to determine if cattle with various foraging experiences could facilitate location of feeding sites by other cattle. Heifers assigned as "followers" (n=24) were initially trained to expect straw at the end of each arm. Initial training of heifers assigned as "leaders" (n=12) differed based on the three following treatments:(1) no-experience, (2)...
متن کاملErythropoietin Improves Place Learning in an 8-Arm Radial Maze in Fimbria-Fornix Transected Rats
Systemically administered human recombinant erythropoietin (EPO) may have the potential to reduce the cognitive and behavioral symptoms of mechanical brain injury. In a series of studies, we address this possibility. We previously found that EPO given to fimbria-fornix transected rats at the moment of injury could substantially improve the posttraumatic acquisition of an allocentric place learn...
