A: Comparison of coherence between thalamus and cortical regions: there was significantly increased overall coherence between thalamus in MTBI patients compared to controls (P<0.05 shown with white bars). Almost all increased thalamo-cortical (BA regions) coherence comes predominantly from low frequency band (0.01-0.08Hz). B: There was positive correlation between low-frequency thalamo-cortical coherence averaged across all cortical BA regions over low-frequency band and post concussive syndrome score (PCS) in MTBI patients (Spearman rank r=0.4, P=0.029).
