The Relationship between Extracellular and Intracellular Slow Waves
Intracellular microelectrode measurements from smooth muscle cells are very difficult to obtain and simultaneous multicell intracellular measurements have never been reported. For these reasons, the majority of in vitro slow wave studies have used extracellular pressure electrodes of the type described by Bortoff (1). An understanding of the relationship between extracellular pressure electrode slow wave signals and their related intracellular potential variations is necessary to obtain maximum information from extracellular studies.
