Fig. S3.

Spearman’s ρ values for the analysis shown in Fig. 3 (based on DMN activity in 10 s), here repeated using single whole-brain volumes before and after the thought-probe onset (rather than averaging across brain volumes). Whole-brain volumes were acquired every 1.08 s. Because thought-probes were self-paced, the time between thought-probe onset and brain volume acquisition varied slightly from probe to probe. Thus, the TR numbers and corresponding time (s) on the x axis denote the upper limit of the possible time between thought-probe onset and volume acquisition (e.g., –2.16 s indicated on the plot denotes a range of –1.08 s to –2.16 s). DMN, default mode network; SC, signal change; TR, repetition time.
