Popis:	A method is described for fabrication of 7-barrelled microiontophoresis electrodes with a center barrel of platinum-coated tungsten. The electrodes require a minimum of expensive apparatus and can be fabricated in an hour or two. The electrodes have low recording impedance (typically 100 kΩ and low resistance iontophoresis barrels (typically 20–50 MΩ). Compared to electrodes with a micropipette recording barrel, these electrodes are practically noise-free and can pass ionotophoretic currents of up to 200 nA without an appreciable increase in recording noise.
