Top: Regions showing transient recollection effects identified by the GLM analysis. Bottom: Regions showing sustained recollection effects are displayed. Effects are projected onto SPM’s single subject rendered brain and are also displayed on sections of the mean across-subjects normalized anatomical image. Mean parameter estimates for two representative regions are plotted across time from −2 to 10s from test item onset. The (MNI) coordinates of the individual voxels from which time courses were derived are (A) −27, −34, −14, and (B) −33, −67, 46. These FIR-derived time courses were extracted separately for each maintenance interval trial type, and, prior to collapsing across maintenance interval, were truncated at 8s, 10s, 12s, and 14s post item onset (for 2, 4, 6, and 8s maintenance interval trials, respectively) to avoid potential contamination of the time course data with BOLD activity associated with the following trial (see Vilberg & Rugg, 2012 where the same procedure was employed). Standard errors are displayed for each estimate. CR = correct rejection.
