In physiology, thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat flux. It deals with a series of events and processes required for an organism to receive a temperature stimulus, convert it to a molecular signal, and recognize and characterize the signal in order to trigger an appropriate defense response.
Thermoception in larger animals is mainly done in the skin; mammals have at least two types. The details of how temperature receptors work are still being investigated. Ciliopathy is associated with decreased ability to sense heat; thus cilia may aid in the process.[1] Transient receptor potential channels (TRP channels)[a] are believed to play a role in many species in sensation of hot, cold, and pain. Vertebrates have at least two types of sensor: those that detect heat and those that detect cold.[4]
