title: The effect of cell excision and microelectrode perforation on membrane resistance measurements of Nitella translucens.
abstract: The effect of cell excision and microelectrode perforation on the membrane resistance measurements of Nitella translucens was determined by direct experiment. From the results it is concluded that perforation has no effect on cells as short as 1 cm. Current leakage though the node of an excised cell has however to be given some consideration. The method used for determining the resistance recovery to insertion has a wide application and its simplicity will encourage its use in other biological systems.
