Sensory capacity (see sense) to detect the temperature of the environment and the body. Thermoreception functions to keep the body temperature stable by regulating behavioral and autonomic responses to temperature changes (see homeostasis). Temperature sensations are generated by peripheral thermoreceptors that detect hot and cold stimuli. Blood-sucking insects and some snakes (e.g., the pit viper) locate prey by its thermal radiation.
