Figure 1
Corrected and uncorrected temporal signal-to-noise ratio (tSNR) values for five regions of interest (ROIs) over all datasets.
The values are derived from the mean tSNR values of both hemispheres. Error bars are standard errors. Corrected tSNRs are equal to the uncorrected tSNRs divided by the volume of a single voxel. IFG, …

Group-level statistical parametric maps (SPMs) of the three main contrasts of the stop-signal task (SST).
Activation colours indicate false discovery rate (FDR) thresholded (q < 0.05) z-values. Two sagittal, one axial, and one zoomed in coronal view are shown. Coloured contour lines indicate regions of …

Group-level statistical parametric maps (SPMs) of the three main contrasts of the stop-signal task (SST), where SS and FS trials were time-locked to the presentation of the stop signal.
Activation colours indicate false discovery rate (FDR) thresholded (q < 0.05) z-values. Two sagittal, one axial, and one zoomed in coronal view are shown. Coloured contour lines indicate regions of …

Group-level z-scores from the region of interest (ROI)-wise general linear model (GLM) analysis of included datasets.
Thresholds are set using false discovery rate (FDR) correction (q < 0.05), varying between contrasts. The thresholds for each contrast are as follows: 3.01 for FS > GO, 2.26 for FS > SS, and 3.1 for …

Figure 3—figure supplement 2
A comparison of the BFs and the frequentist z-scores from FSL.
The 0 point on each axis represents no evidence for an effect. Large absolute z-values are expected to also yield a high log BF, hence the inverted U-shape shows good correspondence between the two …
Figure 4
Log-transformed Bayes Factors for each contrast based on parameter estimates from first-level model.
Colouring depicts evidence for each hypothesis based on a variation of Jeffreys’ scale. BFs more than 2 or less than 2 on a log scale are defined as extreme evidence. Refer to Table 4 for details on …

Comparison of group-level statistical parametric maps (SPMs) for the SS > GO contrast using different smoothing kernels.
SPMs resulting from general linear models (GLMs) computed on base-level spatially smoothed data can be seen on the top row, with SPMs resulting from GLMs computed on data spatially smoothed with a …
