As can be seen from Table 1, frontal theta power was significantly correlated with parietal and occipital theta power (r = 0.60 to 0.70). Likewise, frontal alpha (r = 0.63–0.70) and beta power (r = 0.70–0.82) was significantly correlated with alpha and beta power respectively at parietal and occipital scalp locations. Theta, alpha and beta power was highly correlated with theta, alpha and beta power respectively between parietal and occipital locations (r = 0.80–0.91). All results were significant (p<0.0001, 1df).
