title: Technical note about simultaneous recording of oxygen partial pressure and neuronal activity in cat cortex.
abstract: A method is described for simultaneous measurements of pO2 and action potentials with microelectrodes using prefabricated gold wires. The construction and measuring with such gold electrodes is easier than with traditionally used platinum electrodes. Single electrodes recording is done with a specially adapted electronic circuit, allowing the separation of both signals (pO2 and action potentials. A measurement in cat brain illustrates this procedure.
