Figure 4: Changes of the driving effect between nodes in the semantic cognition network between the left HS, right HS, and normal controls. (i) The driving effect between nodes in ipsilateral structures increased and it decreased between nodes of contralateral structures in patients with left HS. (ii) Directional interaction weight changes between normal and patients with right HS seemed rather systematic, as an increased causal connectivity change was accompanied with a decreased intensity change and vice versa. (iii) The node degree of the right PCC was significantly different between patients with left HS and controls, and the node degree of the right MTG was significantly different between patients with right HS and controls.
