Effects of the neonicotinoids thiametoxam and clothianidin on in vivo dopamine release in rat striatum.

Thiamethoxam (TMX) and clothianidin (CLO) are neonicotinoids insecticides. The main characteristic of these pesticides is their agonist action on nicotinic acetylcholine receptors (nAChRs). In the present work it was studied and characterized the effects of TMX and CLO, in different concentrations, on dopaminergic system of rat striatum using in vivo brain microdialysis coupled to HPLC-EC.
