  • The positive charge that they carry produces a further membrane depolarization, which activates additional sodium channels, so depolarizing the membrane even further.
  • The ability of the plasma membrane to depolarize remains functional in the rho cells as evidenced by the release of insulin with the depolarizing agent KCl.
