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. 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.

WebThe radial arm maze was designed by Olton and Samuelson in 1976 to measure spatial learning and memory in rats. [1] The original apparatus consists of eight equidistantly spaced arms, each about 4 feet long, and all radiating from a small circular central platform (later versions have used as few as three [2] and as many as 48 arms [3] ). 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.
