Maguire et al. (2003) compared brain activity during the encoding of visual stimuli of digits, faces, or snowflakes. When they analyzed the fMRI data, they found that superior memorizers (SMs) had increased activity ________ where performance of the SMs was the same as performance of controls.
A) in the occipital cortex and anterior hippocampus, even during the snowflake task
B) in the medial parietal cortex, retrosplenial cortex, and right posterior hippocampus, even during the snowflake task
C) in the occipital cortex and anterior hippocampus, but only during the snowflake task
D) in the medial parietal cortex, retrosplenial cortex, and right posterior hippocampus, but only during the snowflake task

Maguire et al. (2003) found that superior memorizers had increased activity in the medial parietal cortex, retrosplenial cortex, and right posterior hippocampus, even during tasks where their performance matched that of control participants, such as the snowflake task. This suggests that the brain regions involved are not task-specific but rather are generally engaged during memory tasks by individuals with superior memory abilities.
