CALCIUM AND POST-TETANIC HYPERPOLARIZATION OF BULLFROG SYMPATHETIC GANGLION CELL MEMBRANE

摘要

The PTH of bullfrog sympathetic ganglion cells consists of two different components viz. the initial rapid component and the late slow component. The late slow component is augmented in the presence of TEA. The analysis of the late slow component suggests that this component is produced by an increase in potassium conductance of the membrane, which is caused by an increase in calcium influx during the action potential of the ganglion cells.
