Pretraining affects Morris water maze performance with different patterns between control and ovariectomized plus d-galactose-injected mice

There is little literature addressing the influences of the repeated Morris water maze (MWM) test on behavioral performance under physiological and neurodegenerative conditions. The results revealed that pretraining had distinctively different effects on MWM performances of vehicle control mice and Alzheimer's disease model mice induced by ovariectomy plus injection of d-galactose after an 8-w interval. This interference effect should be considered during analyzing behavioral outcomes using repeated MWM tests.
