Molecule that activates nociceptors by interacting with a temperature-sensitive ion channel and is the basis for "hot" sensations in spicy food. Some transmembrane receptors are activated by chemicals called ligands. Such low frequency vibrations are sensed by mechanoreceptors called Merkel cells, also known as type I cutaneous mechanoreceptors. For humans, the only electromagnetic energy that is perceived by our eyes is visible light. For example, losing sight can compel you to use your other senses more.
