Abstract
Isolated rat dorsal root ganglion neurons have been perfused with potassium-free solutions containing cAMP, ATP and Mg2+ ions. In these conditions stable inward calcium currents can be recorded in the somatic membrane of all investigated cells. The kinetics of these currents can be approximated by a modified Hodgkin-Huxley equation using a square power of the m-variable; its inactivation is extremely slow. The corresponding channels pass Ba2+ ions about twice more effective than Ca2+.
