How does the brain primarily interpret the strength of a stimulus in the nervous system?

A. Based on the size of the action potential

B. Based on the frequency of the action potential

C. Based on how much potassium is in the nerve cell

D. Based on which chemicals are released at nerve junctions

Answer:B. Based on the frequency of the action potential.

The brain primarily interpret the strength of a stimulus in the nervous system based on the frequency of the action potential.

Answer: Option B

Explanation:

The sign that is transmitted down the axon is called action potential. It passes quickly through the axon. At the axon terminal the entry of the action potential by and large causes the arrival of a transmitter that influences the layer of the objective neuron.

The activity possibilities imprint times at which the cell layer at the neuronal cell body arrives at the terminating limit. In this manner, there is an arrangement of action potential containing data about the layer potential at the neuronal cell body.

It is the data conveyed by the train of activity possibilities that gives data at the projection focuses for the neurons. Thus it is inferred that brain uses the frequency of the action potential to interpret the primary stimulus.
