Abstract
The selection of tungsten microelectrodes for cellular-level recordings is frequently based on simple testing techniques, such as microscopic examination and generation of gas bubbles on the exposed tip. A rapid technique, whereby the relative impedance magnitude may be determined using swept frequencies, is described.
