To create a good and authentic replica of an object, there is to be a skilled artisan or forger to create the same authentic experience that the original object provides. This process takes time and much money to be done correctly for museum standards.
Asker's rating. Report Abuse. A threshold potential is the level at which an action potential will fire. For example, if a cell has a resting membrane potential of -90mEV, and the threshold potential is -60mEV, a stimulus must depolarize the membrane by 30mEV to cause the action potential to fire.
Suppose that the net summation of EPSPs and IPSPs is a depolarization that brings the membrane potential of the trigger zone of the postsynaptic neuron to -60 mV. Since -60 mV is below threshold, an action potential will not occur in the postsynaptic neuron.
