source level task-related theta activities (dB) and phasic pupil diameter (baseline-corrected) in each condition and session. The x-axis refers to the time window of pupil diameter, which is 0 to 2 s; the y-axis refers to the time window of theta activity, which is 0 to 1 s. Only significant coefficients (p ≤ . 05) are shown. Black areas represent non-significant coefficients (p > .05). Red lines mark the boundaries of the negative correlation clusters of interest in each plot. The correlation coefficient (r) is colour coded. Warm colours denote positive correlations coefficients, cold colours negative correlation coefficients.
Correlation between theta activity and pupil diameter. Figure parts (A–H) shows the correlation coefficient matrix between
