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).
Finally, when all these forces balance out, and the difference in the voltage between the inside and outside of the neuron is measured, you have the resting potential. The resting membrane potential of a neuron is about -70 mV (mV=millivolt) - this means that the inside of the neuron is 70 mV less than the outside. At rest, there are relatively more sodium ions outside the neuron and more potassium ions inside that neuron.
