Abstract
Electrical measurements were done on glycerol-treated crayfish muscle cells with intracellular recording.
1. Decrease of the resting membrane potential was caused by van Harreveld solution containing glycerol (100mM-2M).
2. Glycerinated muscles responded to the change of external potassium concentration with changes in membrane potential.
3. The effective resistance of the cell membrane was decreased and local action potentials were reduced in glycerinated muscle.
4. The reduced action potential was restored to normal by application of ATP dissolved in van Harreveld solution at concentration of 0.1 per cent.
