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. 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].
