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]. WebApr 9, 2024 · It was conducted on day 22 and day 23. During the training phase (day 22), each rat was placed on one end of the open arm with its face pointing away from the center square. Each rat was allowed to explore the maze for 120 s. The time taken for each rat to enter and reach the end of the closed arms is known as the transfer latency (TL).
