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 most neurons at rest is: more positive than the equilibrium potential for potassium. The diffusion potential due to the concentration gradient for Na+ across a nerve cell membrane: favors its movement into the cell at the resting membrane potential.
