extending into the right parahippocampal gyrus and medial right precuneus (relevant for visual and linguistic processing, learning and memory). In addition, non-AU youth showed significant activation in the left hippocampus during novel encoding, whereas AU youth did not. The authors suggest that this pattern of greater right superior prefrontal activation during learning may reflect AU youths' reliance on frontal memory networks, potentially as an effort to compensate for lower levels of medial temporal lobe (hippocampal/parahippocampal) activation, or increased effort to suppress task-irrelevant information during verbal working memory tasks.
