Relationships between manifolds for mutual information ${\mathcal{M}}_I$ (gray line), stochastic interaction ${\mathcal{M}}_S$ (orange line), and integrated information ${\mathcal{M}}_G$ (green plane) in the Gaussian case. ${\mathcal{M}}_I$ is the line where $A=0$, ${\mathcal{M}}_S$ is the line where $\mathrm{\Sigma }{(E)}_{12}$ and $A_{12},A_{21}$ are 0, and ${\mathcal{M}}_G$ is the plane where $A_{12},A_{21}$ are 0.
