Figure 4.

A conjunction analysis shows overlapping activations between the manipulation (delay phase) and storage (encoding or delay phase) conditions. Regions in red represent activations common to manipulation and storage encoding. Regions in yellow represent activations common to manipulation and storage delay. An overwhelming amount of overlap was observed between the manipulation and storage conditions, indicating that manipulation re-engages substrates specific to the encoding phase and also those specific to phonological rehearsal. Areas unique to manipulation, shown in blue, were notably located in the right prefrontal cortex (slice y = +43) and left inferior cerebellum (slice y = −56). Slice labels are as described in Figure 3.
