Answer :
Final answer:
The strength of a stimulus within the nervous system is coded by the frequency of action potentials produced, not their amplitude. The greater the stimulus, the more rapid and frequent the action potentials, leading to the activation of more receptors.
Explanation:
The strength of a stimulus in the nervous system is coded into the frequency of action potentials generated, as denoted by option A. The more intense a stimulus, the more frequent the action potentials produced by the sensory receptor, forming a rapid train of action potentials. On the contrary, reducing the stimulus slows down the rate of production of action potentials.
Another factor that helps to encode the intensity of a stimulus is the number of receptors that get activated. An intense stimulus typically gets more receptors activated compared to a less intense stimulus. These action potentials represent electrical signals that travel within the nervous system, facilitating communication between various parts of the body.
