The Fast potential could not be elicited when the external solu- tion was made hypertonic (toad-Ringer + 300 mM sucrose). On the other hand, the Slow potential was only slightly altered under these conditions. Conversely, the addition o£ 2-4 dinitrophenol ( mM) or NaCN (2 mM) to the outer solution caused a complete inhibition of the Slow potential without affecting the Fast potential. ose. ose.
