Electrophysiological Correlates of Long-Term Soto Zen Meditation

Table 2

Correlation index (Spearman ρ) followed by the measure precision index (), relative values and ratio correlations, meditation weekly frequency versus theta/beta ratio of induced band powers, theta relative induced band power, theta/beta ratio of the relative induced band powers, and alpha frequency peak (all values were collected during the passive observation task).

Variable	EBP induced theta/beta ratio 18 Hz; Pas	EBP induced theta/beta ratio 25 Hz; Pas	Relative induced theta; Pas	Relative induced theta/beta ratio; Pas	Alpha frequency; Att.
