Subchronic level of arsenic exposure can affect the level of monoamine neurotransmitters in mice brains. Arsenic can downregulate the concentrations of norepinephrine (NE)‚ dopamine (DA)‚ monoamine oxidase (MAO) and 5-OH tryptamine (5-HT) in the cerebrum or cerebellum of mice. Arsenic increases acetylcholinesterase in brain tissue [7‚ 8]. The oxidative damage results in structural deformities in the myelin sheath of nerve fibers
