Exercise 3 Activity 4: PEX-03-04.  In this experiment a single axon was inserted in the nerve chamber. A nerve is a bundle of many axons. The action potential that is recorded extracellularly for a nerve is called a compound action potential -- the sum of all action potentials in the axons. Suppose a nerve was used instead of a single axon in the experiment. What difference might be seen in the response recorded at R2 when lidocaine was added? Explain.

I understand that lidocaine stopped the responses in R2 eventually by blocking the sodium channels but I don't understand what the difference would be if there were more axons instead of just one. Would they all be blocked the same way the single axon was? Or do they respond differently with more? Not sure if I am making any sense

Look at how lidocaine differs from the other variables.
