Abstract
Differential pulse voltammetry was performed with electrochemically treated C fiber electrodes. By this technique ascorbic acid and catechol compounds were resolved in vitro in 2 distinct peaks. Similar oxidation peaks were obtained in vivo from the striatum of rats and guinea pigs. Electrochemical and pharmacological observations suggest that they correspond to the oxidation of extracellular ascorbic acid and 3,4-dihydroxyphenyl acetic acid (DOPAC).
