Biphasic action potential of mixed nerve except?
Ans. is'b'i.e., Two or more positive peaksAction potential when recorded by putting two electrodes on the surface of a neuron (instead of putting on surface and one intracellularly), shows a biphasic response, i.e. Biphasic action potential.As the wave of depolarization reached the first electrode, this electrode becomes negative and an upward deflection (Peak) is recorded.
