Mean ReHo maps of patients with overt hepatic encephalopathy (lower column) and healthy controls (upper column).

The prefrontal cortex, lingual gyrus, middle temporal gyrus, bilateral precentral gyrus, paracentral lobule and precuneus exhibited significantly higher ReHo values than the global mean ReHo values of both groups (p<0.01, false discovery rate corrected), but had different strengths between the two groups.
