HNG prevented Aβ31–35-induced deficits in spatial learning and memory in rats. A, Average escape latency for finding the hidden underwater platform (aa P < 0.01 compared with control group; bb P < 0.01 compared with 2.0 nmol Aβ31–35 group). B, Percentage of swimming time in the previous target quadrant. HNG alone did not affect the spatial cognitive function but prevented Aβ31–35-induced memory deficits (**P < 0.01). Each point or column represents the mean ± SEM. C. Representative swimming tracks in probe trials on day 6.
