Contrasts of source activity during different stages. The brain scans show t values for contrasts between mean activity in adjacent periods, separately for the (a) encoding-minus-retrieval, (b) retrieval-minus-decision, and (c) decision-minus-response contrasts. The graph (d) shows average residual source activity for the pair-recognition experiment and arithmetic-retrieval experiment after warping every trial, separately for the fusiform (Talairach coordinates: x = −42, y = −60, z = −8), left lateral inferior prefrontal cortex (LIPFC; Talairach coordinates: x = −43, y = 23, z = 24), and motor (Talairach coordinates: x = −42, y = 19, z = 50) regions.
