The control of contraction activation by the membrane potential

  • Published:
Experientia Aims and scope Submit manuscript

Summary

Force measurements under voltage-clamp control were performed in short toe muscles of the frog. The results show a) that the activation of force development and its repriming process can at least qualitatively be correlated to charge movement kinetics; b) that caffeine improves EC coupling by potentiating the potential dependent activation process.
