Fig. 6: Temporal attention phase-shifts anticipatory ITPC modulation.

a Group mean 20 Hz ITPC time series for each precue condition, fit with linear plus 2 Hz periodic models (dashed lines) to the precue-to-T1 period (gray bar). Shaded error regions indicate ±1 standard error of the difference (SED). b No statistically significant differences in the fitted intercept, slope, or amplitude between precue conditions (repeated measures ANOVA p > 0.150). Data are presented as mean values ± 1 SED. c The 2 Hz phase is significantly concentrated on precue T1 trials (left, Rayleigh z test p = 0.035 after Bonferroni correction), and temporal attention phase-shifts the periodic modulation (right, Rayleigh z test p = 0.021 after Bonferroni correction). Shaded histograms show phase distributions across individual participants. n = 10 participants for all panels and statistical tests. ** p < 0.01 uncorrected, p < 0.05 after Bonferroni correction. Source data are provided as a Source Data file.
