Fig. 3: Difference in the directionality of the effective connectivity for visual cortical regions (the rows) with 180 cortical regions (the columns) in both hemispheres when viewing spatial scenes.

For a given link, the effective connectivity difference is shown as positive when the connectivity is stronger in the direction from column to row. For a link, the effective connectivity difference is shown as negative when the connectivity is weaker in the direction from column to row. The threshold value for any effective connectivity difference to be included is 0.0005 for the connectivities shown in Fig. 2. This threshold was chosen to help show which differences were greater than or lesser than zero. Table S1 shows the abbreviations for the cortical regions, and the cortical regions are shown in Figs. 1 and S1. The effective connectivity difference in the top panel is for the first set of 90 cortical regions; and in the lower panel for the second set of 90 cortical regions. The conventions are as in Fig. 2.
