Summary of model components

Parameter	Interpretation
$W_{n\times n}^E$, $W_{n\times n}^I$	Exc.-Exc. and Exc.-Inh. connectivity
1-$D_{n\times 1}^E$, 1-$D_{n\times 1}^I$	Exc. and Inh. decay rates
${\beta }_{n\times 1}^E$, ${\beta }_{n\times 1}^I$	Local Inh.-Exc. and Inh.-Inh. connections
$c_{n\times 1}^E$, $c_{n\times 1}^I$	Tonic drive to exc. and inh. populations
${\epsilon }^E$, ${\epsilon }^I\in {\mathbb{R}}^n$	Extrinsic (unmodeled) activity
${\psi }_E,{\psi }_I:{\mathbb{R}}^n\to {\mathbb{R}}^n$,	Nonlinear activation (output) function

All parameters of these components (including the variance of $\epsilon$) are directly estimated from single-subject timeseries. The estimated connectivity matrices $W^E$ and $W^I$ contain both local (diagonal-elements) and long-distance connections.
