This burning sensation is experienced by most other mammals, and is real, at least according to your brain. Capsacin binds a cellular receptor that is also activated by temperatures exceeding 43 degrees Celcius. The receptor, transient receptor potential cation channel subfamily V member 1 (TRPV1), is responsible for communicating pain and has a role in temperature regulation. Evolutionary pressure has caused capsicum plants to produce capsaicin to...
