Figure 1
Summed outflow of the largest drivers across frequencies.
(a) The summed outflow of the largest drivers across frequencies is illustrated for each group (TD, Left; ASD, Right). (b) Regions consistently showing large driving in both groups for theta and alpha. Summed outflows are represented as spheres: the larger the sphere, the higher the summed outflow. ROIs are displayed on an ICBM Average Brain, axial top view. See acronyms list in Table 2.
Figure 2
Summed outflow differences in the ASD group compared to their typically developing peers.
(a) On the left, the 6 ROIs with a statistically significant different summed outflow in the ASD group compared to their TD peers for the theta band. On the right, the 3 ROIs with a statistically significant different summed outflow in the ASD group compared to their TD peers for the alpha band. A red nod indicates increased driving, a blue nod indicates decreased driving. Corresponding ROIs are displayed on an ICBM Average Brain, with sagital, axial and corronal views. (b) Boxplots with the summed outflow values comparing each group for each significant ROI in the theta band. (c) Boxplots with the summed outflow values comparing each group for each significant ROI in the alpha band. The boxplots display the full range of variation of the summed outflows (from min to max), rectangles span the interquartile range and the median. See acronyms list in Table 2.
Figure 3 with 2 supplements
Region-to-region directed functional connectivity for the theta band (4–7 Hz) from each of the six significant ROIs represented as large red spheres.
Outflows are represented as arrows: the larger the arrow, the stronger the outflow. ROIs and connections are displayed on an ICBM Average Brain, axial and coronal views. See acronyms list in Table 2.
Figure 3—figure supplement 1
ORBsup.R seed (large red sphere) for the ASD group in theta band.
Boxplots with the outflow values comparing each group for each connection. Outflows are represented as arrows: the larger the arrow, the stronger the outflow. The boxplots display the full range of variation (from min to max) of the outflow values, rectangles span the interquartile range and the median. See acronyms list in Table 2.
Figure 3—figure supplement 2
ORBsup.R seed for the (large red sphere) for the TD group in theta band.
Boxplots with the outflow values comparing each group for each connection. Outflows are represented as arrows: the larger the arrow, the stronger the outflow. The boxplots display the full range of variation (from min to max) of the outflow values, rectangles span the interquartile range and the median. See acronyms list in Table 2.
Figure 4
Region-to-region directed functional connectivity for the alpha band (8–12 Hz) from each of the three significant ROIs, represented as large red spheres.
Outflows are represented as arrows: the larger the arrow, the stronger the outflow. ROIs and connections are displayed on an ICBM Average Brain, axial and coronal views. See acronyms list in Table 2.
Figure 5
Significant correlations after FDR correction between the summed outflow in theta for the ASD participants (represented as blue dots) and (a) standardized VABS-II scores, (b) PEP-3 standardized scores and (c) Proximity Index.
(d) Significant correlations after FDR correction between the summed outflow in alpha and PEP-3 standardized scores. TD summed outflow values are plotted on the Y axis in red. Corresponding ROI are displayed on an ICBM Average Brain, axial top view.
Figure 6
Exemplar single time frame of the normative gaze pattern for each group on one random time frame.
Each dot represents the gaze position for an individual participant. The face has been blurred on purpose to preserve anonymity but was fully visible for the participants during the experiment.
