This Article contained an error in the Figure legends of Figure 3 and Figure 4. The legends of these Figures were inadvertently switched.
The legend of Figure 3:
“Gamma phase-synchrony between occipital and parietal electrodes. wPLI (30–60 Hz) for visual imagery (
A) and control (
B) conditions. (
C) Cluster-based permutation test comparing visual imagery and control conditions. The area highlighted in the time–frequency chart depicts a significant wPLI cluster between conditions (visual imagery minus control) in the gamma band (30–60 Hz). (
D) Region of interest (ROI) for phase-synchrony analysis. wPLI values are expressed in standard deviations (z-scores) in reference to the baseline (− 1500 to − 1250 ms). Trial length (− 1500 ms) is relative to response time (0 ms). (
D) Topographical representation of occipitoparietal wPLI channel pairs and single-participant wPLI values for the imagery (left) and control (right) conditions. Each arc represents a pair of channels, and the height of the arc is its normalised value. Grey circles represent single-participant wPLI values for the cluster depicted in (
C) for the imagery (left panel) and control (right panel) conditions. The red horizontal line represents the group mean, the rectangle represents SEM, and the red-dashed horizontal line represents the group median.”
now reads:
“Theta phase-synchrony between inter-hemispheric frontal electrode pairs. wPLI (1–10 Hz) for visual imagery (
A) and control (
B) conditions. (
C) Cluster-based permutation test comparing visual imagery and control conditions. The area highlighted in the time–frequency chart depicts a significant wPLI cluster between conditions (visual imagery minus control) in the theta band (5–7 Hz). (
D) Region of interest (ROI) for phase-synchrony analysis. Only interhemispheric frontofrontal pairs of channels were considered for the analysis (see Sect. 2.8 for details). wPLI values are expressed in standard deviations (z-scores) in reference to the baseline (− 1500 to − 1250 ms). Trial length (− 1500 ms) is relative to response time (0 ms). (
