Schematic representation of the functional connectivity associated with shyness.

(A) Regions showing positive correlations between functional connectivity and shyness (seeds located in right superior temporal gyrus and left cerebellum posterior lobe; (B) Regions showing negative correlations between functional connectivity and shyness (seeds located in bilaterally parahippocampal gyri); (C) Regions showing both positive and negative correlations between functional connectivity and shyness (seeds located in the bilateral amygdalae). Scatter plots on the right show correlations between regional functional connectivity (FC) value and shyness and social anxiety scores.
