Regions with GM changes showing positive and negative correlations between functional connectivity and shyness without other anxiety correction.

Shyness scores are significantly correlated with functional connectivity in left cerebellum (A), right insula (B), bilateral superior temporal gyri (C&D), and bilateral parahippocampal gyri (E & F) seeds. Images are presented in radiological orientation. Hot and cold colors indicate brain regions with significant positive (hot) and negative (cold) correlations with shyness.
