Suprathreshold graded potentials within a neuron can generate ________action potential(s) at the axon hillock, which allows for the________of the magnitude of the stimulus.
A) multiple : frequency coding
B) a single : frequency coding
C) several : amplitude coding
D) a single : amplitude coding
E) multiple : amplitude coding

Question

Quizplus · Accepted Answer

Suprathreshold graded potentials can generate multiple action potentials at the axon hillock. The frequency of these action potentials, rather than their amplitude (which remains constant due to the all-or-none principle), codes for the magnitude of the stimulus. This is known as frequency coding.
