Which of the following electrical signals exhibit local excitation characteristics?

Aaction potential in a nerve fiber
Baction potential in a nerve trunk
Cspike potential
Dendplate potential

Correct answer: D. endplate potential

Endplate potentials are graded potentials that can sum up to produce an action potential but do not reset the membrane potential to the resting level, thus exhibiting local excitation characteristics.
