Verified step by step guidance

Understand that the brain interprets the intensity of a stimulus based on the frequency of action potentials. Action potentials are electrical signals that neurons use to communicate.

Recognize that a higher frequency of action potentials indicates a stronger stimulus. This is because more frequent signals can convey more information about the intensity of the stimulus.

Consider that the type of neurotransmitter released can affect the nature of the signal, but it is not directly related to the intensity of the stimulus.

Note that the duration of the stimulus can affect how long the brain perceives the stimulus, but it does not directly indicate intensity.

Understand that the location of the stimulus helps the brain determine where the stimulus is coming from, but it does not provide information about the intensity.
