thermoreceptor
Quick Summary
Thermoreceptors are specialized sensory receptors that detect temperature. In humans, these receptors are primarily located in the skin and are responsible for sensations of warmth and cold. Some thermoreceptors are highly specific, responding only to thermal stimuli, while others are polymodal, reacting to temperature as well as chemicals like capsaicin or menthol.1
Mammals also possess thermoreceptive elements in their brains, particularly in the spinal cord and hypothalamus, which play a role in regulating body temperature. These receptors send signals through neural pathways to the brainstem and forebrain, ultimately leading to conscious perception of temperature and influencing behaviors related to thermoregulation.234

The study of thermoreceptors began when minute areas of the skin were found to be selectively sensitive to hot and cold stimuli. In animals thermoreception can be studied in different ways—for example, through observations of behavioral responses to variations in temperature, through measurement of…

The concept of thermoreceptors derives from studies of human sensory physiology, in particular from the discovery reported in 1882 that thermal sensations are associated with stimulation of localized sensory spots in the skin. Detailed investigations revealed a distinction between warm spots and cold spots—that…
