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. Since, by convention, the potential outside the cell is defined as zero, the. resting potential (Vr) is equal to Vin. Its usual range in neurons is -60 mV to -70 mV.
