The rate off increase regarding conductance develops constantly since the membrane layer potential is actually shorter
Both salt and you may potassium conductance go up collectively an enthusiastic inflected curve when new membrane are depolarized. Both slip with no appreciable inflections when the membrane try repolarized. The rate out of slide out-of conductance reduces in the event that membrane layer possible is actually enhanced. Additionally, the rise and you will slip of your salt conductance takes place 10-29 minutes reduced compared to the involved pricing having potassium. The fresh new version away from top conductance which have membrane prospective is deeper to possess salt than for potassium. If your axon are depolarized, the brand new potassium conductance are handled but the sodium conductance refuses after getting their top.
(Figure step 1: Into left-hand column, big date course of the potential difference in the internal and exterior electrode. Just the right give column shows brand new membrane most recent date movement getting the brand new related membrane potential found regarding the left-hand column)
(Contour dos: Membrane layer newest big date programmes from the depolarization out-of 97.5mV lastking 0.05, 0.08, 0.19, 0.thirty-two, 0.91, 1.six, and dos.six msec)
(Contour step three: Membrane current of the depolarization from 110mV, lasting 0.twenty-eight msec. Nerve A is actually sea-water. Courage B is during chlorine drinking water. Bravery C had an excellent depolarization of 220mV and that’s inside chlorine water)
