The concentration in brain of both octopamine (OCT) and tyramine (TYR) was significantly increased in rats 8 weeks after portal-systemic bypass. This suggests that the increase in OCT is secondary to increased decarboxylation of tyrosine to TYR. However, the role these neuroamines, particularly OCT, play in the development of hepatic encephalopathy remains controversial.
