Question 8

Why do we perceive chili peppers as "hot" and peppermint as "cold"?

Accepted Answer

A) It is a cultural convention to speak of chili peppers as hot and peppermint as cold. 
B) Capsaicin and menthol act as agonists of TRP channels normally activated by temperature changes. 
C) We are conditioned to think so because chili-containing foods are served hot, while mint-containing foods are served cold. 
D) Neurons sensitive to heat or capsaicin project to nearby regions of the brain, while neurons sensitive to cold or menthol project to other adjacent regions.
