No significant clusters

Shown are locations of main cluster activation peaks (MNI coordinates) and Z scores for brain regions showing a significant Time × CI interaction effect from DAY1 to DAY3 acquisition phase in YA (Z > 2.3; cluster significance: p < 0.05, corrected). R, Right; L, left; CER, cerebellum; CR1, crus 1; SFG, superior frontal gyrus; ACC, anterior cingulate cortex.
