nociception

Pain is a sensation transmitted from sensory nerves through the spinal cord and to the sensory area of the cerebrum, where the sensation is perceived. It is defined by the International Association for the Study of Pain (IASP) as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage”.
