fMRI thought-monitoring task. In the nonmonitor condition participants slid a cursor sideways along a scale to match a target circle. In the monitor condition, participants slid the cursor along the scale to indicate how internally oriented or externally oriented their thoughts were (see Materials and Methods). The two conditions were matched for visual and motor features, but differed in the thought-monitoring component.
- Figure 2.
VBM differences between the two lucidity groups. The high-lucidity group showed greater GM volume in two separate clusters within BA9/10, in right ACC, left SMA and hippocampus bilaterally. Results are corrected for minimum cluster extent and nonstationary smoothness (Hayasaka et al., 2004).

Behavioral results in the thought-monitoring task A, Distribution of responses for the thought-monitoring task on the continuous internal–external scale for each of the lucidity groups. B, Mean RTs (solid lines) and MTs (dashed lines) for the monitor and nonmonitor conditions. Error bars represent SEM, and asterisks indicate significant differences (p < 0.05).
- Figure 4.
fMRI results in the thought-monitoring task. Extracted percentage signal change from a spherical 5 mm ROI around the peak voxel of each of the three clusters within frontal cortex (bottom displays the cluster from which the spherical ROIs was built). Error bars represent SEM, and asterisks indicate significant differences (p < 0.05).
