The temporal resolution of carbon-fiber microelectrodes has been exploited to examine the plasticity of quantal secretory events at individual adrenal medullary cells. The size of individual quantal events, monitored by amperometric oxidation of rele

Secretion of catecholamines from individual bovine adrenal medullary cells in culture was examined by amperometry with 1-micron radius carbon-fiber electrodes. Vesicular secretion is observed as a series of current spikes upon exposure to a secretago

Cyclic voltammetry at Nafion-coated carbon fiber microclectrodes has been used to monitor directly the release of catecholamines from individual adrenal medullary chromaffin cells and to identify the released catecholamine as epinephrine or norepinep
