Normally the brain determines the strength of a taste sensation from the a. rate of nerve impulses received

b. size of nerve impulses received

c. part of the tongue that is stimulated

d. part of the brain that receives the impulse

Answer: Option C) part of the tongue that is stimulated

Explanation:

On touching a substance, the nerve ending of the tongue is stimulated. The impulses are transmitted through the sensory neuron into the brain. From there, impulses are relayed to the intermediate neuron and then goes to the effector organ which brings about an interpretation of strength of the taste sensation

Thus, the strength of taste sensation depends on the part of the tongue that is stimulated.
