Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| one-step state-space model instead of two-step MNE then AR fit | dynamic connectivity estimation (A_t and Q) · Simulated MEG, a=2 and a=5 | relative estimation error of A_t and Q | Helped |
| time-varying (vs. static) AR coefficients in state-space model | dynamic connectivity in scene-processing MEG · Real MEG scene processing, one participant | significant lagged dependence between EVC and PPA | No clear effect |
| one-step state-space model vs two-step MNE on real MEG data | EVC-PPA lagged dependence · Real MEG scene processing, 362 images | plausibility of early significant clusters | Mixed |
