Relationship between working memory and cortical thickness during development.

Significant, cluster-wise corrected, clusters from linear mixed models on vertex-wise thickness analyses. Blue-cyan indicates a negative relationship between thickness and WM scores. LCBC: The relationship between WM (indexed Digit Span Backwards, Digit Span Forwards and Digit Span Total) and cortical thickness, controlling for sex, age and scanner. The baseline age cut-off ; for the developmental group was ≤ 16.9 years. At follow up, the ages of these participants ranged from 4.4 to 26.7 years. ABCD: the relationship between List Sorting WM Test scores and cortical thickness (9.0–10.9 years), controlling for sex, age and ethnicity.
