Specificity of nAChRs-mediated currents in SCG neurons.
Representative nAChR current traces evoked by ACh alone (control), coapplied with 100 µM hexamethonium bromide and ACh alone (recovery), respectively. 100 µM hexamethonium bromide, a special nAChR antagonist, completely blocked the currents induced by 200 µM acetylcholine.
