SpletPolychlorinated biphenyls (PCBs) exposure produces profound damage to the developing as well as adult central nervous system. Locomotor activities which are closely linked to dopaminergic neurotransmission are often impaired in PCBs toxicity. Targeting PCBs-induced oxidative stress using natural antioxidants is an attractive approach. SpletPolychlorinated biphenyls (PCBs) are a group of highly toxic endocrine-disrupting chemicals comprising 209 homologs. PCBs are extensively found in the environment and can induce typical estrogenic and profound, long-lasting effects on animals.
