Microarray gene expression profiling of forebrain white matter tissues from hepatic encephalopathy and alcohol abuse patients.
Forebrain white matter tissues were obtained from frozen human post-mortem brains of alcohol abuse patients without hepatic encephalopathy (n=4), alcohol abuse patients with hepatic encephalopathy (n=3) and neurologically normal control subjects (n=3).
White matter was sampled from the prefrontal cortex and the motor cortex.
