• 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.
