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 22, 2013 · Using radial arm maze procedures [17], rats quickly learn to visit each arm only once in a session to retrieve a food reward. Accurate performance is thereby dependent on both memory for previously visited arms and a natural tendency not to revisit arms within a trial, referred to as “win-shift” strategy [18].
