WebThe radial arm maze is constructed with a center platform with arms radiating from the center. The original maze had 8 spokes, but they have been constructed with as few as 3 and as many as 48 spokes. This type of maze is used to perform short-term memory experimentations on rats. WebPairs of rats were tested in a radial-arm maze to determine whether the spatial choices made by one rat affect the subsequent spatial choices of the other rat.

WebApr 8, 2024 · General Conclusions. Using a statistical method more suitable for analysing the sort of censored data typically seen during the acquisition phase of the standard Morris water maze, our results demonstrate that post-weaning social isolation can improve the spatial learning and memory ability of both male and female rats. WebFigure 66.5. Radial arm maze. A radial arm maze is a test of hippocampal function. A central platform is surrounded by several arms radiating away from the center. At the end of one arm is a small dish that contains food, but the other arms do not have food. The rodent must explore the arm to discover if it has food or not.

WebYoung adult (8 months) and aged (26 months) female Wister rats were tested in a 12-arm radial maze in which the optimal strategy was to enter all arms without a repetition.

WebThe radial arm maze or Olton spatial maze consists of an central area with eight arms extending from it. Exploratory behavior is measured by the total number of arm entries and the number of different arm entries. WebRats pretrained in a radial arm maze performed better in a water maze than non-pretrained rats. No difference between groups was found in a non-spatial water maze task. On the other hand, when pretrained in a water maze, rats performed only marginally better in a radial arm maze compared to non-pretrained animals.

WebRats with excitotoxic lesions of the dorsal or ventral hippocampus and control rats were trained on 2 spatial working memory tasks: the standard version of the radial maze with 8 baited arms and the nonmatching-to-place procedure in the T maze.
