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.
A stimulus from a sensory cell or another neuron depolarizes the target neuron to its threshold potential (-55 mV), and Na channels in the axon hillock open, starting an action potential. Once the sodium channels open, the neuron completely depolarizes to a membrane potential of about +40 mV.
