If you applied tiny amounts of ACh to muscle, you get excitatory postsynaptic potentials (epsps) on individual muscle fibers. When a muscle is stimulated, however, action potentials are also fired and obscure the epsps. What manipulation can be done to mask the action potentials, thereby revealing the underlying epsps?
A) The application of tiny amounts of ACh
B) The application of tiny amounts of tetrodotoxin
C) The application of tiny amounts of curare
D) The application of substantial amounts of ACh
E) The application of substantial amounts of sodium
