Values are speeds (means ± SE) from each maze epoch during the physostigmine conditions and resulting Pearson r values (means ± SE) from correlations of speed with theta, low gamma, and high gamma power. ANOVA for age group × physostigmine shows no difference in the magnitude of the correlation after drug injections.
