A focus on mechanisms fundamental thermal nociception and hyperalgesia is largely because of the identification of your TRP household of channels.
Pain receptors, also called nociceptors, are specialised nerves that detect problems or opportunity harm to tissue and transmit this information and facts towards the brain. The human body then sends out protective responses for instance wincing or withdrawing from painful stimuli.
