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

<p>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 (<i>p</i><0.01, false discovery rate corrected), but had different strengths between the two groups.</p>
