Values are speeds (means ± SE) from each maze epoch during the saline condition and resulting Pearson r values (means ± SE) from correlations of speed with theta, low gamma, and high gamma power. An ANOVA for age group × environment (env) shows no difference in the magnitude of the correlation between adult and old rats, although the novel maze decreased this correlation for both age groups. n.s., Not significant.
