Monoamines and metabolites in autopsied brain tissue from cirrhotic patients with hepatic encephalopathy.
TL;DR: Findings show that selective alterations of catecholamine and 5-HT systems are involved in human HE and therefore, they may play an important role in the pathogenesis of certain neurological symptoms associated with this encephalopathy.

Monitoring of neurotransmitter amino acids by means of an indwelling cisterna magna catheter: A comparison of two rodent models of fulminant liver failure
TL;DR: Sequential measurements of amino acids in the cerebrospinal fluid of small rodents with indwelling cisterna magna catheters adds a useful new approach for exploring the neurobiology of hepatic encephalopathy in fulminant liver failure.

Aromatic and branched-chain amino acids in autopsied brain tissue from cirrhotic patients with hepatic encephalopathy.
TL;DR: In this paper, the branched-chain amino acids (BCAAs) valine, leucine, and isoleucine were measured in three areas of dissected brain tissue obtained at autopsy from nine cirrhotic patients who died in hepatic encephalopathy.

Regional alterations of dopamine and its metabolites in rat brain following portacaval anastomosis.
TL;DR: Increased DA turnover thus appears to relate to early neuropsychiatric and extrapyramidal symptoms of PSE, and did not worsen at coma states of P SE.

TL;DR: Levels of phenylalanine and tyrosine levels in brain tissue of cirrhotic patients, and levels of the 5-HT metabolite, 5-hydroxyindoleacetic acid (5-HIAA), were found to be increased, and amino acid precursors of monoamines, monoamines and some of their metabolites were measured in homogenates of prefrontal cortex.
