Thermoreceptors

Butterflies have photoreceptors in their penises that guide mating behavior (leading to the phenomenon termed "hindsight"), and crayfish have "caudal photoreceptors" and thermoreceptors that can drive walking behavior without the involvement of the brain (Arikawa, Suyama & Fujii, 1997; Wilkens, 1988). ❋ Maggie Koerth-Baker (2011)

For comparison, the same approach was applied to the sensation of warmth elicited by thermoreceptors. ❋ Coturnix [email protected] (2010)

Individual thermoreceptors have ongoing activity at static constant temperatures of 30°C or more, following a bell-shaped curve with maximum discharges at 40-43°C ❋ Léon Plaghki Et Al. (2010)

Also, humans might have thermoreceptors, like thylakoids inside plants enabling photosynthesis, that permit radio waves to trigger a cascade of chemical events. ❋ Unknown (2010)

- Anterior - heat loss - Posterior - heat production • receives input from two sets of thermoreceptors: - receptors in the hypothalamus itself monitor the core temperature - receptors in the skin monitor the external temperature. • sends impulses to several different effectors to adjust body temperature ❋ Unknown (2009)

These are classified into five types of sensory receptors, the mechanoreceptors, photoreceptors, chemoreceptors, thermoreceptors and electroreceptors. ❋ Unknown (2008)
