Nociceptor activation is determined because of the pain stimulus: this depends on the positioning of technology and manner of activation. The internet site of application of your stimulus is crucial because it can impact the intensity from the nociceptor reaction. An interesting case in point is the fact that of corneal nociceptors, which might be activated by weaker stimuli than skin nociceptors are [five]. The nature from the stimulus is additionally vital.
