Fig. 6: The joint distribution of FS alpha and theta and joint entropy (JE).
From: Alpha and theta peak frequency track on- and off-thoughts

a The joint distribution of alpha/theta FS (and FP). Off-multiple and on-single’s distribution could be discriminated in FS with overlaps. b The joint entropy (JE) results in FS. JE values for off-multiple thoughts are significantly higher than those for on-single thoughts. The error bar means SD. ****p < 0.0001.
