Solution

The central nervous system interprets the strength of a stimulus based on "The frequency of action potential generated by sensory cells".

Here's a step-by-step explanation:

  1. A stimulus (like touch, heat, light, etc.) is detected by sensory cells (also known as sensory neurons) in our body. These cells have the ability to convert the stimulus into an electrical signal known as a receptor potential.

  2. The size of the receptor potential can affect the amount of open gated ion channels in the sensory cell. The larger the receptor potential, the more ion channels open.

  3. However, the central nervous system does not interpret the strength of a stimulus based on the size of the receptor potential or the amount of open gated ion channels. Instead, it's based on the frequency of action potentials.

  4. Action potentials are the 'messages' that neurons send to communicate. They are essentially bursts of electrical activity. The more frequently these action potentials are generated, the stronger the central nervous system interprets the stimulus to be.

So, the strength of a stimulus is interpreted by the frequency of action potentials generated by sensory cells.
