Fig. 2: MEG Effective connectivity for visual cortical regions (the rows) with 180 cortical regions (the columns) in both hemispheres when viewing spatial scenes.

The effective connectivities are the mean across both directions for every pair of cortical regions. Effective connectivities of <0.03 are shown as white to help reveal the main effective connectivities between the cortical regions. The effective connectivity map is scaled with 0.14 as the maximum. The effective connectivity 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 abbreviations for cortical regions are shown in Table S1. Horizontal red lines separate the groups of visual cortex regions. Group 1: (top) early visual cortical areas V1–V4 in the HCP-MMP atlas; Group 2: cortical regions in the retrosplenial complex; Group 3: ventromedial visual cortical regions; Group 4: parahippocampal cortex regions; Group 5: hippocampal and related regions; Group 6: intermediate ventrolateral cortical visual regions FFC (fusiform face cortex), PIT (posterior inferior temporal cortex), and V8. Group 7: inferior temporal visual cortex regions TE2p and TE1p. Group 8: anterior temporal lobe multimodal regions including the temporal pole TGd and TGv. The coloured labelled bars indicate the cortical divisions in the HCP-MMP atlas⁵⁵. The order of the cortical regions on the horizontal axes is that in Huang, ref. ¹²⁰.
