Remembered objects. Intra-regional activations associated with Rem responses, as compared with Fam, during the episode retrieval (cf. bar 1 vs bar 2, in each plot). This comparison showed activation of the left hippocampus/parahippocampus (HC/PHC, top panel, in cyan), the precuneus (PreC, in magenta) and the ventro-medial prefrontal cortex (vmPFC, in green). The same comparison also showed significant activation of the left lateral temporal cortex (visible in the top-left coronal section) and the occipital cortex (visible in the 3D rendering). Activations are displayed at p-FWE-corr = 0.05, corrected for multiple comparisons at the whole brain level (T-value = 4.9, min. cluster size = 10 voxels). Rendering was done using MRIcron⁵¹. The signal plots show the parameter estimates at the peak-voxel and for all the episode-retrieval conditions. These include correctly recognized new-items (“NEW Corr”) and incorrect responses (“Wrg”, plotted separately for old/seen and new/unseen trials). The parameter estimates of the general linear model are mean-adjusted (sum = 0) and negative values should not be interpreted as de-activations.
