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).
Hyperpolarization and depolarization. At rest, a typical neuron has a resting potential (potential across the membrane) of â60-60â60minus, 60 to â70-70â70minus, 70 millivolts. This means that the interior of the cell is negatively charged relative to the outside.
