An easily constructed carbon fiber recording and microiontophoresis assembly.
Traditional multibarreled pipette electrodes are still widely used in microiontophoresis studies. Although better electrodes have been introduced, they are difficult and time-consuming to make. Construction of a carbon fiber recording and microiontophoresis assembly is described here. The construction of a carbon fiber electrode assembly is easy and carbon fibers have excellent characteristics for recording extracellular single unit activity. Signal-to-noise ratio of the carbon fiber electrode is maintained when combined with microiontophoresis. The electrode assembly can be used repeatedly, if cleaned properly, and it can be used to make marking lesions upon completion of an experiment.
