The nociceptor is characterized by its response to noxious heat, stress, or chemical stimuli. The ''pain'' information is coded in the sample and frequency of impulses during the axons of the key afferent nociceptors. You will find a immediate relation among the intensity on the stimulus along with the frequency of nociceptor discharge (Determine seven-3).
