Abstract
Catecholamines such as dopamine, nor - epinephrine and epinephrine at different intervals were analyzed in the brain regions of chlorpyrifos treated Rattus norvegicus and the catecholamine levels mimic the extrapyramidal symptoms like parkinsonism. However, the levels of catecholamine were restored significantly as that of control due to atropine, pyridine aldoxime methiodide, reserpine and propranolol treatment over a period of 24 h.
