Fig. 9 — Panels A, B, C and D show different variations of coherency of trial-to-trial variability and scan noise across two voxels (SOA = 2 s and both trial SD and scan SD = 0.5). In each Panel, plots on left show parameters/estimates for 30 trials of each of two trial-types: true parameters (β_j) for trials 1–30 are 5 and 3 for voxel 1 and voxel 2 respectively, while true parameters (β_j) for trials 31–60 are 3 and 5 for voxel 1 and voxel 2 respectively. Plots on right show difference between voxels for each trial (which determines CP). Upper plots in each panel show corresponding parameter estimates ( ${\hat{β}}_{j}$ ) from LSA model; lower plots show estimates from LSS-2 model.
