Aistimiskynnysarvot, also referred to as thermoreceptors, are specialized sensory neurons found in the peripheral nervous system that detect changes in temperature. These neurons are capable of perceiving both increases and decreases in temperature, ranging from very low to very high levels.

There are two main types of thermoreceptors: cold-receptors and heat-receptors. Cold-receptors, located in the skin, are activated by decreases in temperature and respond to temperatures below room temperature. Heat-receptors, also found in the skin, are activated by increases in temperature and respond to temperatures above room temperature.

Thermoreceptors play a crucial role in maintaining homeostasis and are essential for detecting changes in temperature, which can be caused by various factors such as the environment, physical activity, or inflammation. They send signals to the brain, where they are processed and interpreted, allowing the body to respond to changes in temperature.

Information from thermoreceptors is not only important for maintaining physical comfort but also for proper regulation of the body's internal temperature, or core temperature. Disruptions to this process can have serious consequences, such as changes in mental performance, cardiovascular strain, or even heatstroke or hypothermia.

Research on thermoreceptors has also led to a greater understanding of their role in pain perception. Studies have shown that certain types of pain, such as cold and heat pain, are mediated by the same pathways as temperature sensation. This has implications for the development of new treatments for chronic pain conditions.
