Post differentials. (a). A post differential may be granted on the basis of conditions of environment which differ substantially from conditions of environment in the continental United States and warrant additional pay as a recruitment and retention incentive.
We will also see that in order for a neuron to generate an action potential, the membrane potential has to depolarize from the resting value of around â70 mV to the threshold value of around â50 mV. A similar situation is also at play in muscle cells (skeletal, cardiac, and smooth).
The membrane potential of a cell at rest is called the resting membrane potential. resting potential (Vr) is equal to Vin. Its usual range in neurons is -60 mV to -70 mV. potential due to alterations in the flow of electrical current across the cell membrane resulting from the opening and closing of ion channels.
