✦ Synopsis

The existence in a population of aging rats of classes that display a different performance in the Morris water-maze test was investigated by cluster analysis procedure. These classes identified at 18 months of age showed a different response to levocarnitine acetyl and had a different behavioral profile when tested at 25 months of age. These findings demonstrate the need for an alternative interpretation of variability in animal populations as measured by the standard statistical analyses. The data analysis strategy we propose here will allow for the use of variability as a useful source of information.

## Abstract The mechanism by which tooth loss accelerates spatial memory impairment is unknown. The purpose of this study was to test the hypothesis that tooth loss affects trkB‐mRNA levels and leads to an accelerated decrease in the hippocampal cell density in rats. A radial maze was used to evalu

Nicotine improves working memory function in a variety of different testing situations. In a series of studies, we have found that chronic nicotine infusion improves working memory performance of rats in the win-shift version of the radial-arm maze. In the current studies, we examined the interactio
