Question

A nerve is a bundle of axons, and some nerves are less sensitive to lidocaine. If a nerve, rather than an axon, had been used in the lidocaine experiment, the responses recorded at R1 and R2 would be the sum of all the action potentials (called a compound action potential). Would the response at R2 after lidocaine application necessarily be zero? Why or why not?

Answer 1

Answer:

the response at R2 after lidocaine application will not be zero

Explanation:

The response at R2 after lidocaine would not be zero because it is recording the of all action potentials and some axons may be unaffected.
