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).
In most resting neurons, the potential difference across the membrane is about 30303030 to 90909090 mV\text{mV}mVm, V (a mV\text{mV}mVm, V is 1/10001/10001/10001, slash, 1000 of a volt), with the inside of the cell more negative than the outside.
