Analysis of specific anatomic regions exhibiting significant effects. A, Left, Red represents a region containing at least two spatial ROIs and that was part of a significant cluster in both the asymmetry index analysis (Fig. 2C) and the time scaling factor analysis (Fig. 3D). Right, Mean similarity map for the region indicated in A, left. Similarity map is computed using all correct trials for each electrode in the region, averaged across electrodes within a participant and across participants. Color represents average cosine similarity. Asymmetry indices (a − b) are shown above the similarity plot. Horizontal black line indicates the first-time bin where all the data are from after pair presentation during encoding. Vertical black line indicates the first-time bin where all the data are from after cue presentation during retrieval. Diagonal black line is the t_enc = t_ret line. B, Same as A for additional region satisfying the same criteria as the region in A.
