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).
At the axon hillock of a typical neuron, the resting potential is around â70 millivolts (mV) and the threshold potential is around â55 mV. Synaptic inputs to a neuron cause the membrane to depolarize or hyperpolarize; that is, they cause the membrane potential to rise or fall.
