Quantitative depiction of the DTI fiber counts for each connection between the thalamic seeds and the target regions. The numbers indicate the means (±SD) of counted connections for all 23 subjects, corrected for seed volumes.
Please note that the less numerous cortical connections might be affected by technical limitations of DTI, and do not necessarily represent the same degree of anatomical connectivity. Statistical thresholds:
P < 0.001,
P < 0.01 indicate significantly greater fiber counts for one thalamic region (MD or CM/Pf) compared to the other.
ai/fo: anterior insula/frontal operculum; dACC: dorsal anterior cingulate cortex; dlPFC: dorsolateral prefrontal cortex; PCC: posterior cingulate cortex; pgACC: pregenual anterior cingulate cortex.
