Which of the Following BEST Describes the Response of Thermoreceptor

Which of the following BEST describes the response of thermoreceptor afferents when temperature decreases from 35°C to 25°C?

A) Warm- receptor afferents show a decrease in the frequency of action potentials, whereas cold- receptor afferents show an increase in the frequency of action potentials.
B) Warm- receptor afferents show a decrease in the frequency of action potentials, whereas cold- receptor afferents fire at the same frequency.
C) Afferents associated with both warm and cold receptors show a decrease in the frequency of action potentials.
D) Warm- receptor afferents show an increase in the frequency of action potentials, whereas cold- receptor afferents show a decrease in the frequency of action potentials.
E) Afferents associated with both warm and cold receptors show an increase in the frequency of action potentials.
