Association of subjective effects measures with variance in the BOLD signal in left and right claustrum, insula, and putamen regions of interest. Statistics are limited to equations involving a subjective effect that significantly predicted ALFF in at least one region of interest. ß = standardized regression coefficient of the independent variable. Equations where the independent variable is significant (critical α = 0.05, uncorrected) are presented in bold font. MEQ: mystical experience questionnaire.
