Description of the models used to test the effective connectivity of the regions. Model (a) receives the input at the SMA, which is connected unidirectionally to M1S1. Model (b) receives the input at M1S1; both regions are connected bidirectionally. Model (c) has inputs going to both the SMA and M1S1; both regions are connected bidirectionally. All models have a one‐way connection from M1S1 to the posterior insula. Models (d) through (f) are similar to models (a) through (c), with the exception of a bidirectional connection between M1S1 and insula.
