Search-related deactivations, dissociated from activity due to memory strength, were observed in
regions of the default network, whereas distinctly strength-dependent activations were present in
superior and inferior parietal and dorsolateral PFC. Both search and strength regulated activity in
dorsal anterior cingulate and anterior insula. These findings suggest that, although highly
correlated and partially subserved by overlapping cognitive control mechanisms, search and
memory strength engage dissociable regions of frontoparietal attention and default networks.
