Extracellular potassium activity during frequency-dependent conduction block of giant axons in the metathoracic ganglion of the cockroach.


In the metathoracic ganglion (T3) of the cockroach, extracellular potassium activity (aK) was measured with ion-sensitive microelectrodes and intracellular recordings were simultaneously made from giant axons (GAs) during high frequency stimulation of the connectives. Blockade of spike conduction through T3 was associated with intraganglionic aK rises of 0… (More)
