A similar analysis performed on the group of experiments with significant PFC-HC correlation at 2–5 Hz (n=13) showed the same result (r = 0.74 ± 0.05 and r = 0.01 ± 0.1, before and after partialization for 2–5 Hz). Partial correlation analysis on the entire population (n=15, using original correlation values without zeroing non-significant correlations) also consistently showed elimination of PFC-HC 2–5 Hz correlation when controlling for nRE (r = 0.68 ± 0.06 to r = 0.006 ± 0.1), but no effect on theta correlation theta (r = 0.38 ± 0.09 and r = 0.40 ± 0.1), or on any other combination of signals for either 2–5 Hz or theta correlation.
