Spatial activation maps of the task-related components and associated time courses. (A) Positive memory retrieval of the older adults. (B) Negative memory retrieval of the older adults. (C) Positive memory retrieval of the younger adults. (D) Negative memory retrieval of the younger adults. The statistical threshold was set at p < 0.05, corrected for multiple comparisons through FDR with a minimum cluster of 5 contiguous significant voxels. The solid line indicates the time courses of task-related components, and the dotted line indicates the reference function. r represents the correlation coefficient between the time course of the task-related component and the reference function.
