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).
Most often the threshold potential is a membrane potential value between â40 and â55 mV, but it can vary based upon several factors. A neuron's resting membrane potential (â70 mV) can be altered to either increase or decrease likelihood of reaching threshold via sodium and potassium ions.hreshold tracking allows for the strength of a test stimulus to be adjusted by a computer in order to activate a defined fraction of the maximal nerve or muscle potential.
