Both dopamine and norepinephrine play major roles in critical neuronal pathways linked to motor function, cognition, emotion, memory, and endocrine modulation. Impairments in catecholaminergic neurotransmission occur in response to methylmercury (MeHg) exposure. This chapter will focus on the toxic effects of MeHg on the catecholaminergic system, emphasizing the neurological consequences resulting from MeHg exposure, as well as related mechanisms of neurotoxicity.
